Description

[Technical Field]

[0001] The present invention relates to a feline excretion suppression composition and a method for suppressing feline excretion. [Background technology]

[0002] The history of pets is long, and cats, in particular, have been kept since ancient Egypt, either as pets like we know them today or for practical purposes such as rodent control. Today, many animals such as dogs, cats, rabbits, and small birds are kept as pets, and they have become well-established as familiar companion animals closely intertwined with human daily life. While dogs and cats are the most representative of these animals, recently the number of dogs kept as pets has been declining, while the number of cats kept as pets has been increasing, with cats now outnumbering dogs. Although keeping cats indoors is becoming more common, many cats are still allowed to roam freely. This, along with stray cats not owned by humans, leads to problems such as cats venturing into unintended areas and causing inconvenience to humans. In particular, problems related to cat feces and urine have developed into a major social issue due to their strong odor and the effort required to clean them up. Furthermore, many owners of indoor cats are troubled by "inappropriate urination" (defecating outside of the litter box) and "spraying," a form of marking behavior. To solve this problem, many repellents have been disclosed, such as those that use repellents that cats and dogs dislike, as well as those that repel cats using ultrasound or holographic sheets (Patent Documents 1-3, etc.). However, the repellent effect of these methods is not sufficient, and even if cats are temporarily repelled, the situation quickly returns to normal, resulting in problems with the persistence of the repellent effect. As a result, damage caused by excrement such as feces and urine has not been adequately suppressed. [Prior art documents] [Patent Documents]

[0004] The present invention aims to provide a feline excretion suppression composition and a method for suppressing feline excretion. [Means for solving the problem]

[0005] The inventors of this invention have conducted extensive research to solve the above problems and have found that by treating the treated area with a composition containing one or more selected from sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds as active ingredients, cat excretion is suppressed not only in the treated area but also in a wide area surrounding it, and damage caused by excrement such as feces and urine is greatly reduced, thus solving the above problems.

[0006] The present invention is summarized in the following terms: 1. A feline excretion inhibitory composition containing one or more active ingredients selected from sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds. 2.1. A method for suppressing excretion in cats, characterized by treating the cat excretion-suppressing composition described above. [Effects of the Invention]

[0007] By treating an area with the feline excretion-suppressing composition of the present invention, it is possible to suppress cat excretion not only in the treated area but also in a wide area surrounding it. Moreover, since the present invention achieves its excretion-suppressing effect by making cats recognize that the treated area is not a place to excrete, it is possible to maintain the excretion-suppressing effect for a long period of time even if the concentration of the active ingredient in the composition decreases. While cats are often perceived as solitary creatures, free-roaming cats and stray cats that live outdoors frequently form groups and live together. This invention allows not only some cats but the entire group of cats to recognize areas treated with the cat excretion-suppressing composition as not being places to defecate, thereby achieving a significant excretion-suppressing effect. Furthermore, it is useful not only for toilet training of indoor cats but also for suppressing the aforementioned "inappropriate excretion" and "spraying behavior." Furthermore, although the details will be described later, the feline excretion-suppressing composition of the present invention has been confirmed not to be accidentally ingested or swallowed by cats, and is therefore highly safe. For example, it can be used with confidence for toilet training of indoor cats. [Brief explanation of the drawing]

[0008] [Figure 1] This graph shows the results of "Test 1 to Confirm the Effect of Inhibiting Excretion in Cats" in the example. [Figure 2] This graph shows the results of "Test 2 to Confirm the Effect of Inhibiting Excretion in Cats" in the example. [Figure 3] This graph shows the results of "Test 3 to Confirm the Effect of Inhibiting Excretion in Cats" in the example. [Modes for carrying out the invention]

[0009] The following describes in detail the feline excretion-suppressing composition and the method for suppressing feline excretion according to the present invention. All cats, including those kept entirely indoors, have the instinct to establish a "territory" and live within it. Free-roaming cats and stray cats share their territories with other cats, and therefore have the instinct to patrol and inspect their territory daily. Cats not only defecate and urinate in one or more designated "litter boxes" within their territory, but they also engage in marking behavior called "spraying" to assert their territory. Because the urine of cats that use this marking function emits a strong odor, it becomes a major problem. On the other hand, cats are very clean animals and are sensitive to smells, so they have a habit of clearly separating the area where they defecate and urinate from the area where they eat. The inventors hypothesized that this behavior is a manifestation of cats recognizing separate areas for defecation and eating. They considered that if areas where feces and urine damage occurs could be made to be recognized and learned by cats as eating areas, the damage could be reduced, and conducted investigations. As a result, it was found that when cat food-like fragrance compounds were applied to areas where feces and urine damage occurred, defecation behavior in those areas was suppressed immediately after application. In particular, among the food-like fragrance compounds, sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds were found to strongly suppress defecation behavior in the treated areas immediately after application, thus completing the present invention. The feline excretion-inhibiting composition and method of feline excretion-inhibiting in the present invention are based on the fact that cats distinguish and recognize the place where they excrete and the place where they eat, and learn this distinction. This is fundamentally different from repellents that use odors or components that cats dislike to keep them away. As will be explained in detail in the examples described later, the effects of the feline excretion-inhibiting composition and method of feline excretion-inhibiting in the present invention continue even after the active ingredient has disappeared, whereas with repellents, the repellent effect is lost as soon as the active ingredient disappears.

[0010] The feline excretion-suppressing composition of the present invention contains one or more selected from sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds as an active ingredient. <Sulfur-containing compounds> In this invention, sulfur-containing compounds refer to compounds also known as organic sulfur compounds, meaning organic compounds containing sulfur atoms. While sulfur-containing compounds are generally recognized as compounds with unpleasant odors, they are known to exhibit strong and distinctive aromas at low concentrations, and are particularly used as meat-like, especially cooked meat-like, aroma compounds. As the sulfur-containing compound in the present invention, a compound having a molecular weight in the range of 50 to 250 is preferable, a compound having one or two sulfur atoms in one molecule is more preferable, and particularly, a sulfide compound or a disulfide compound is preferable. Specific examples of the compound suitable as the sulfur-containing compound in the present invention include dimethyl sulfide, 2,4-dithiapentane, 3-(methylthio)propanal, dimethyl sulfone, furfuryl methyl disulfide, difurfuryl disulfide, and the like.

[0011] <Saturated fatty acid> The saturated fatty acid in the present invention is a monovalent carboxylic acid of a hydrocarbon that has no double bond or triple bond in the carbon chain and is saturated with hydrogen. Saturated fatty acids are contained in large amounts in meat, milk, butter, egg yolk, chocolate, cocoa butter, coconuts, palm oil, etc., and are particularly known as aroma components unique to dairy products. As the saturated fatty acid in the present invention, a compound having a boiling point in the range of 210 to 400 °C is preferable, and among them, a saturated fatty acid having 7 to 18 carbon atoms is preferable, and a saturated fatty acid having 7 to 9 carbon atoms is more preferable. Specific examples of the compound suitable as the saturated fatty acid in the present invention include heptanoic acid (7 carbon atoms, boiling point: 223 °C), octanoic acid (8 carbon atoms, boiling point: 240 °C), nonanoic acid (9 carbon atoms, boiling point: 254 °C), and the like.

[0012] <Saturated aliphatic hydrocarbon compound> The saturated aliphatic hydrocarbon compound in the present invention is a hydrocarbon compound that has no double bond or triple bond in the carbon chain and is saturated with hydrogen. The saturated aliphatic hydrocarbon compound is known as an aroma component of dried bonito flakes. As the saturated aliphatic hydrocarbon compound in the present invention, a compound having a boiling point in the range of 210 to 320 °C is preferable, and among them, a saturated aliphatic hydrocarbon compound having 12 to 18 carbon atoms is preferable, and a saturated aliphatic hydrocarbon compound having 12 to 14 carbon atoms is more preferable. Suitable saturated aliphatic hydrocarbon compounds in the present invention include, specifically, dodecane (12 carbon atoms, boiling point: 214-216°C), tridecane (13 carbon atoms, boiling point: 234°C), and tetradecane (14 carbon atoms, boiling point: 253-255°C).

[0013] The content of the active ingredient in the feline excretion-inhibiting composition of the present invention is not particularly limited and can be set as appropriate, but it is preferably 0.5 ppb to 10% by weight, more preferably 0.5 ppm to 3% by weight, and even more preferably 0.001 to 2% by weight relative to the total feline excretion-inhibiting composition. Below 0.5 ppb, a good feline excretion-inhibiting effect cannot be obtained, and above 10% by weight, not only does the feline excretion-inhibiting effect not change significantly, but it may also produce an irritating odor for humans, which is undesirable.

[0014] <Pharmaceutical Products> The feline excretion-suppressing composition of the present invention contains one or more active ingredients selected from sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds, and is usually used as a formulation. The formulation form can be appropriately determined depending on the intended use. For example, it can be in the form of an oil, emulsion, wettable powder, granules, powder, spray, aerosol, coating, cleaning agent, sheet, or injection. Preferred formulation forms include granules and powders prepared as a liquid and impregnated into a porous solid carrier such as zeolite, as well as spray formulations such as sprays and aerosols prepared as a liquid. Among these, granular and powder formulations are convenient because they can be easily applied by sprinkling them on horizontal surfaces where cat excretion suppression is desired, while aerosol formulations and other spray formulations are suitable because they can be easily applied to vertical surfaces where cat excretion suppression is desired.

[0015] In preparing the liquid formulation of the feline excretion-suppressing composition of the present invention, nonionic, anionic, cationic, and other surfactants may be added as needed. Specifically, examples include nonionic surfactants such as alkylaryl ethers, polyoxyethylene derivatives of alkylaryl ethers, polyethylene glycol ethers, polyethylene glycol fatty acid esters, polyoxyethylene fatty acid esters, polyoxyethylene polyoxypropylene copolymers, polyoxyethylene hydrogenated castor oils, polyhydric alcohol esters, and sugar alcohol derivatives; anionic surfactants such as alkyl sulfate salts, alkyl sulfonates, and alkylaryl sulfonates; and cationic surfactants such as alkylammonium halides. Among these, when the stock solution of the feline excretion-suppressing composition of the present invention is an aqueous solution, it is preferable to add nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene alkylphenyl ethers, polyoxyethylene hydrogenated castor oils, glycerin fatty acid esters, alkyl glyceryl ethers, polyoxyethylene glyceryl ethers, and polyoxyethylene sorbitan fatty acid esters.

[0016] The feline excretion-suppressing composition of the present invention may also contain other known liquid carriers, gaseous carriers, solid carriers, and other formulation aids. Examples of liquid carriers include aromatic or aliphatic hydrocarbons (xylene, toluene, alkylnaphthalene, phenylxylethane, kerosene, diesel fuel, hexane, cyclohexane, liquid paraffin, etc.), halogenated hydrocarbons (chlorobenzene, dichloromethane, dichloroethane, trichloroethane, etc.), alcohols (methanol, ethanol, isopropyl alcohol, butanol, hexanol, benzyl alcohol, ethylene glycol, etc.), ethers (diethyl ether, ethylene glycol dimethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, propylene glycol monomethyl ether, tetrahydrofuran, dioxane, etc.), and esters. Examples include (ethyl acetate, butyl acetate, isopropyl myristate, ethyl lactate, ethyl benzoate, etc.), ketones (acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, etc.), nitriles (acetonitrile, isobutyronitrile, etc.), sulfoxides (dimethyl sulfoxide, etc.), heterocyclic solvents (sulfolane, γ-butyrolactone, 1,3-dimethyl-2-imidazolidinone), acid amides (N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone, 3-methoxy-N,N-dimethylpropionamide, etc.), alkylidenes (propylene carbonate, etc.), vegetable oils (soybean oil, cottonseed oil, etc.), vegetable essential oils (orange oil, hyssop oil, lemon oil, etc.), and water.

[0017] Examples of gaseous carriers include butane gas, chlorofluorocarbons (CFCs), alternative CFCs (such as HFOs and HFCs), liquefied petroleum gas (LPG), dimethyl ether, nitrogen gas, and carbon dioxide. Examples of solid carriers include clays (kaolin, diatomaceous earth, bentonite, clay, acid clay, etc.), zeolites, talc, ceramics, other inorganic minerals (sericite, quartz, sulfur, activated carbon, calcium carbonate, hydrated silica, etc.), and porous materials.

[0018] Other pharmaceutical additives include binders, dispersants, solubilizers, and stabilizers, specifically, for example, casein, gelatin, polysaccharides (starch, gum arabic, cellulose derivatives, alginic acid, etc.), lignin derivatives, sugars, synthetic water-soluble polymers (polyvinyl alcohol, polyacrylic acid, etc.), benzoic acid esters and salts, BHT (2,6-di-tert-butyl-4-methylphenol), and BHA (a mixture of 2-tert-butyl-4-methoxyphenol and 3-tert-butyl-4-methoxyphenol). In the present invention, rust inhibitors, preservatives, pH adjusters, fragrances, and other components may be added as needed. These components may be those commonly used in this field. Specifically, examples of rust inhibitors include Karen No. 955, No. 906, No. 954, No. 958, and No. 970 (all trademarks: Sanyo Chemical Industries, Ltd.). Examples of preservatives include methyl parahydroxybenzoate, ethyl parahydroxybenzoate, propyl parahydroxybenzoate, butyl parahydroxybenzoate, isothiazolinone, sodium salicylate, sodium benzoate, phenoxyethanol, potassium sorbate, and sodium dehydroacetate. Examples of pH adjusters include organic acids such as acetic acid, lactic acid, succinic acid, maleic acid, tartaric acid, citric acid, ascorbic acid, salicylic acid, and benzoic acid, as well as inorganic acids such as phosphoric acid and their salts.

[0019] When describing the case in which the feline excretion-inhibiting composition of the present invention is made into granules or powder, for example, a liquid formulation obtained by dissolving or dispersing one or more active ingredients selected from sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds in water with a nonionic surfactant can be supported on a porous solid carrier such as zeolite to make granules or powder. Examples of porous solid carriers such as zeolite that can be used include powders, spheres, and pellets of about 0.1 to 10 mm, with spheres or pellets of about 1 to 5 mm being preferred. These granules and powders can be used by scattering them in areas where you want to suppress cat excretion, or by storing them in a breathable bag or container and placing or setting them in areas where you want to suppress cat excretion.

[0020] When describing the case in which the feline excretion suppression composition of the present invention is filled into an aerosol spray container to form an aerosol, a wide range of known propellants can be used, such as butane gas, fluorocarbon gas, alternative fluorocarbons (such as HFO and HFC), liquefied petroleum gas (LPG), dimethyl ether, nitrogen gas, and carbon dioxide. In the feline excretion suppression composition of the present invention, the amount of propellant can be 10 to 95% by volume of the total feline excretion suppression composition, particularly 30 to 90% by volume. When manufacturing the feline excretion-suppressing composition of the present invention as an aerosol, a wide range of methods commonly used in this field can be employed. Representative methods include mixing one or more active ingredients selected from sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds, heating them as needed (30-50°C) to create a homogeneous solution, then adding rust inhibitors, preservatives, etc., placing the resulting stock solution into an aerosol spray container, filling it with a propellant, and producing the final product. The aerosol formulation of the feline excretion-suppressing composition of the present invention obtained in this manner is stable and maintains a uniform state even under harsh conditions over long periods, and can be sprayed as fine particles with a single touch to treat areas where feline excretion needs to be suppressed.

[0021] The present invention's feline excretion-inhibiting composition can be used as a spray by, for example, dissolving or dispersing one or more active ingredients selected from sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds in water with a nonionic surfactant, and then filling a spray container with the resulting liquid formulation. Any spray container that can easily be filled with a liquid formulation and has a spraying function is acceptable, but considering versatility and high spray accuracy, trigger-type spray containers or mist-type spray containers are preferred, and trigger-type spray containers are particularly preferred. This trigger-type spray container has a pistol-shaped trigger-type spray device attached to the mouth of the container body into which the contents are filled, and the spray can be operated at atmospheric pressure, making it a highly versatile spray container. The term "trigger-type spray container" as used here includes all trigger-type spray containers that have been modified to enhance the spraying function.

[0022] The cat excretion-suppressing composition of the present invention can suppress cat excretion by treating areas where cat feces and urine are not desired, whether indoors or outdoors. This effect is achieved because cats recognize the treated area as unsuitable for excretion. Therefore, even if the concentration of the active ingredient in the cat excretion-suppressing composition of the present invention decreases, the excretion-suppressing effect can be obtained for a long period of time, which is fundamentally different from general cat repellents. The feline excretion-suppressing composition of the present invention can suppress the excretory behavior of cats by applying 0.01 μg or more of the active ingredient in the composition per square meter of treated surface. For a more sufficient effect, use 0.02 μg to 5 g / m². 2 More preferably 0.02 mg to 3 g / m² 2 More preferably 0.01 to 1 g / m 2 Applying this should suffice. [Examples]

[0023] The present invention will be described in more detail below with reference to formulation examples and test examples, but the present invention is not limited to these examples. In the examples, unless otherwise specified, "parts" refers to parts by weight.

[0024] <Test 1 to confirm the effect of suppressing excretion in cats> (1) Preparation of test specimens One part by weight of dimethyl sulfide was dissolved in ten parts by weight of isopropyl myristate, and this was uniformly supported on 89 parts by weight of zeolite with a particle size of 2-3 mm to obtain the test sample for Example 1. Examples 2 and 3 were prepared using the formulations shown in Table 1 below, and test samples were obtained in the same manner as in Example 1. The active ingredient in Example 3, "Fragrance Composition A," is a blended fragrance containing dimethyl sulfide, octanoic acid, tridecane, 2,4-dithiapentane, 3-(methylthio)propanal, dimethyl sulfone, furfurylmethyl disulfide, and diflufuryl disulfide. In Table 1, "IPM" refers to isopropyl myristate.

[0025] [Table 1]

[0026] (2) Test method for confirming the effect of suppressing excretion in cats A stray cat repeatedly defecates and urinates in a designated area (approximately 1m 2 ) At three locations, 35 g / m² of each test sample (Examples 1-3) was applied. 2 It was spread evenly so as to be the same. Excretion area (approximately 1m 2 One location was left untreated. The day the test samples (Examples 1-3) were applied was considered the start date of the test. At each elapsed time, the presence or absence of feces was checked, and if feces were found, they were removed, and the cumulative number of feces was counted. The results are shown in Figure 1.

[0027] As shown in Figure 1, in the untreated area where nothing was sprayed, the cumulative number of feces was 17 after 4 weeks from the start of the test, whereas in the test sample of Example 3, which contained multiple active ingredients of the present invention, no cat feces were observed for 4 weeks from the start of the test. Furthermore, in the test samples of Examples 1 and 2, which contained only one active ingredient of the present invention, the number of feces was 5 and 2, respectively, over a period of 4 weeks from the start of the test, clearly demonstrating a reduction of approximately 10-30% compared to the untreated area.

[0028] <Test 2 to confirm the effect of suppressing excretion in cats> Using the test sample from Example 3, which demonstrated an extremely excellent cat excretion suppression effect in the "Test 1 for Confirming the Effect of Suppressing Cat Excretion" described above, a test was conducted to compare the cat excretion suppression effect with the active ingredients of commercially available cat repellents. (1) Preparation of test specimens The test sample from Example 3 of the "Test to Confirm the Effect of Inhibiting Excretion in Cats 1" described above was used. Furthermore, Comparative Examples 1 and 2 were prepared using the formulations shown in Table 2 below, and the respective test samples were obtained in the same manner as in Example 1 of the "Test to Confirm the Effect of Inhibiting Excretion in Cats 1" described above. The active ingredients of Comparative Examples 1 and 2, plant essential oil B and methyl salicylate, are active ingredients in commercially available cat repellents, respectively, and plant essential oil B is an essential oil consisting of a mixture of components extracted from herbs (thyme, clove, perilla, etc.). In Table 2, "IPM" refers to isopropyl myristate.

[0029] [Table 2]

[0030] (2) Test method for confirming the effect of suppressing excretion in cats The cumulative number of feces was counted using the same method as in the "Test 1 for Confirming the Effect of Suppressing Excretion in Cats" described above. The results are shown in Figure 2.

[0031] As shown in Figure 2, in the untreated area where nothing was sprayed, the cumulative number of feces after 5 weeks from the start of the test was 18, whereas in the test sample of Example 3, which contains multiple active ingredients of the present invention, there was only one feces from the cat over a 5-week period from the start of the test. This confirmed that, similar to the "Test 1 for Confirmation of Cat Excretion Inhibition Effect" described above, it exhibits an extremely excellent effect in inhibiting cat excretion. Since the excretion-suppressing effect was obtained over a long period of five weeks, it is believed that the excretion-suppressing composition for cats of the present invention exerted its effect because the cats recognized and learned that the treated area was not a place for excretion. In contrast, the test samples in Comparative Examples 1 and 2, which contained plant essential oil B and methyl salicylate, the active ingredients in commercially available cat repellents, showed an inhibitory effect on cat excretion compared to the untreated group for the first two weeks from the start of the test. However, no inhibitory effect was obtained thereafter, and as a result, the cumulative number of feces after five weeks from the start of the test was 18, the same as the untreated group, or even higher at 22. This is thought to be because the cat repellent components in the test samples of Comparative Examples 1 and 2 volatilized after two weeks from the start of the test, resulting in a loss of repellent effect. Based on the results of Example 3, a specific example of the present invention, and Comparative Examples 1 and 2, it is supported that the cat excretion-suppressing composition of the present invention is based on the cat's ability to distinguish and recognize the location of excretion and the location of eating, and to learn this distinction. This is fundamentally different from repellents that use odors or components that cats dislike to keep them away.

[0032] <Test 3 to confirm the effect of suppressing excretion in cats> (1) Preparation of test specimens One part by weight of furfurylmethyl disulfide was dissolved in ten parts by weight of isopropyl myristate, and this was uniformly supported on 89 parts by weight of zeolite with a particle size of 2-3 mm to obtain the test sample for Example 4. The test sample for Example 5 was obtained in the same manner as the test sample for Example 4, except that tridecane was used instead of furfurylmethyldisulfide. In Table 3, "IPM" refers to isopropyl myristate.

[0033] [Table 3]

[0034] (2) Test method for confirming the effect of suppressing excretion in cats The cumulative number of feces was counted using the same method as in the "Test 1 for Confirming the Effect of Suppressing Excretion in Cats" described above. The results are shown in Figure 3.

[0035] As shown in Figure 3, in the untreated area where nothing was sprayed, the cumulative number of feces was 8 after 4 weeks from the start of the test, whereas in the test sample of Example 4, which contained only one active ingredient of the present invention, no cat feces were observed over the 4 weeks from the start of the test. Furthermore, in the test sample of Example 5, which also contained only one active ingredient of the present invention, there was 1 feces during the 3-week period and 3 feces during the 4-week period from the start of the test, clearly demonstrating a significant suppression compared to the untreated area.

[0036] <Test to confirm accidental ingestion of a composition that inhibits feline excretion> (1) Preparation of test specimens The test sample from Example 3 of the "Test to Confirm the Effect of Inhibiting Excretion in Cats 1" described above, along with fragrance composition A and commercially available cat food, were used. Fragrance composition A was used undiluted, impregnated into cotton wool. (2) Test method In the stray cats' territory, test samples from Example 3, fragrance composition A (impregnated directly onto cotton wool without dilution), and commercially available cat food were scattered / placed in areas where the cats repeatedly defecated and urinated, as well as in other areas. The cats' behavior was observed (observation period: August-September 2019, one hour between 10am and 5pm, 6 observations) to confirm whether or not the cats ate the food (including whether or not they licked it). (3) Results In all observations, the commercially available cat food was consumed both in and outside the elimination area, but the test sample of Example 3 and fragrance composition A were not consumed in either the elimination area or outside the elimination area. These results confirm that the excretion-suppressing composition for cats of the present invention is not ingested by cats.

[0037] <Test 4 to confirm the effect of suppressing excretion in cats> (1) Preparation of test specimens The test sample from Example 3 of the "Test to Confirm the Effect of Inhibiting Excretion in Cats 1" described above was used. (2) Test method Individual cats constituting groups A and B were identified, and the area P (100m) within the territory of group A where stray cats constituting group A repeatedly defecate and urinate was identified. 2: Park), and area Q (200m) within the territory of group B where stray cats constituting group B repeatedly defecate and urinate. 2 : Parking lot) was set. When observing the behaviors of each individual constituting groups A and B in area P and area Q (October to December 2019, 16 - 18:00, 6 observation times), it was confirmed that 3 individuals of group A (designating each individual as A - 1, A - 2, A - 3) defecated in area P, and 5 individuals of group B (designating each individual as B - 1, B - 2, B - 3, B - 4, B - 5) defecated in area Q. The number of feces in areas P and Q where defecation behaviors were confirmed was 26 and 10 respectively. After removing the feces confirmed in areas P and Q, the defecation location p (about 33m) 2 where the defecation behavior of individual A - 1 in area P was confirmed, and the defecation location q (about 66m) 2 where the defecation behaviors of 2 individuals B - 1 and B - 2 in area Q were confirmed, were uniformly sprayed with the test sample of Example 3 at 35g / m 2 . Six weeks after the spraying treatment, the presence or absence of feces at each defecation location was confirmed.

[0038] (3) Results Six weeks after the spraying treatment, no feces were confirmed at all in the defecation locations p and q treated with the test sample of Example 3, and also in the locations other than defecation location p in area P (untreated area) and the locations other than defecation location q in area Q (untreated area). From this result, it became clear that an excellent defecation - suppression effect can be obtained over the entire areas P and Q, including not only the defecation locations p and q treated with the test sample of Example 3 but also the locations not treated with the test sample of Example 3. Although the defecation locations p and q are the locations where the defecation behaviors of some individuals (A - 1, B - 1, B - 2) of groups A and B were confirmed, it was confirmed that not only these individuals (A - 1, B - 1, B - 2) but also other individuals (A - 2, A - 3, B - 3, B - 4, B - 5) of groups A and B can obtain a long - term defecation - suppression effect. It has become clear that by applying the cat excretion-suppressing composition of the present invention to only a portion of the area where cat excretion has been confirmed, a long-term effect of suppressing cat excretion can be obtained not only in the treated area but also in a wide surrounding area. [Industrial applicability]

[0039] By treating the treated area with the feline excretion-suppressing composition of the present invention, it is possible to suppress feline excretion not only in the treated area but also in a wide area surrounding it. Moreover, since the present invention achieves its excretion-suppressing effect by making cats recognize that the treated area is not a place to excrete, it is useful because the excretion-suppressing effect can be maintained for a long period of time even if the concentration of the active ingredient in the composition decreases. This invention makes all cats in a group recognize that the area treated with the cat excretion-inhibiting composition is not a place to excrete, thereby achieving a significant excretion-inhibiting effect. Furthermore, the cat excretion-suppressing composition of the present invention is highly safe because cats cannot accidentally ingest or swallow it. For example, it can be used with confidence for toilet training of indoor cats.
