Description

[Technical field]

[0001] The present invention relates to a composition for inhibiting excretion in cats and a method for inhibiting excretion in cats. [Background technology]

[0002] Pets have a long history, and cats have been kept since ancient Egypt as pets, either for practical purposes such as getting rid of mice or for other practical purposes. Today, many animals such as dogs, cats, rabbits, and small birds are kept as pets, and they have become familiar pets that are closely related to human daily life. Dogs and cats are the most representative of these, but while the number of dogs kept as pets has been decreasing in recent years, the number of cats kept as pets has increased, and cats now outnumber dogs in terms of number of pets kept. Although indoor cat keeping is becoming more common, many cats are still kept free to roam, and there are also stray cats that are not kept by humans. These outdoor cats, which enter unintended places and cause problems for humans, are causing problems. In particular, problems with cat feces and other waste have developed into a major social issue due to the strong odor and the effort required to clean up. In addition, many owners of indoor cats are troubled by "inappropriate excretion," which refers to excretion in places other than the litter box, and marking behavior, known as "spraying 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 use ultrasonic waves or holographic sheets (Patent Documents 1 to 3, etc.). However, the repellent effect of these methods is not sufficient, and even if they can repel cats temporarily, they soon return to their original state, so there is a problem with the durability of the repellent effect, and the current situation is that damage caused by excrement such as feces and urine cannot be sufficiently suppressed.

[0004] An object of the present invention is to provide a composition for inhibiting excretion in cats and a method for inhibiting excretion in cats. [Means for solving the problem]

[0005] As a result of intensive research into solving the above-mentioned problems, the present inventors have discovered that treatment with a composition containing as an active ingredient one or more compounds selected from the group consisting of sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds suppresses cat excretion not only in the treated area but also over a wide area surrounding it, thereby significantly reducing damage caused by excrement such as feces and urine, thereby solving the above-mentioned problems.

[0006] Specifically, the present invention relates to the following items. 1. An excretion suppressing composition for cats, comprising as an active ingredient one or more selected from a sulfur-containing compound, a saturated fatty acid, and a saturated aliphatic hydrocarbon compound. 2. A method for inhibiting excretion of a cat, comprising treating the cat with the feline excretion inhibiting composition described in 1. Effect of the Invention

[0007] Treatment with the cat excretion inhibiting composition of the present invention can inhibit cat excretion not only in the treated area but also over a wide area around it. Moreover, the present invention achieves the excretion inhibiting effect by making the cat recognize that the area treated with the cat excretion inhibiting composition is not an excretion area, so that the excretion inhibiting effect can be maintained for a long period of time even if the concentration of the active ingredient in the composition decreases. Cats are often thought of as "solitary creatures," but cats that are free-ranging (free-roaming) or stray cats and other outdoor cats often form groups and live together. The present invention allows not only some cats but all cats that make up the group to recognize a place treated with the cat excretion suppression composition as not an excretion site, and can achieve a significant excretion suppression effect. In addition to training indoor cats to use the "toilet," the present invention is also useful because it can achieve a suppression effect against the above-mentioned "inappropriate excretion" and "spraying behavior." Furthermore, the feline excretion inhibiting composition of the present invention, which will be described in detail later, has excellent safety because it has been confirmed that cats do not accidentally eat or ingest the composition, and can be used safely, for example, for toilet training of indoor cats.

[0009] The feline excretion inhibiting composition and the feline excretion inhibiting method of the present invention will be described in detail below. All cats, including those kept indoors, have the habit of creating a "territory" and living within it. Free-ranging and stray cats share their "territory" with other cats, so they also have the habit of patrolling and inspecting their own "territory" every day. Cats not only excrete urine and feces in one or more "toilets" within their "territory," but also mark their territory through a method known as "spraying" to show off their territory. The urine of cats that have this marking function emits a strong odor, which can be a major problem. On the other hand, cats are very clean animals and sensitive to smells, so they have the habit of clearly distinguishing between the area where they excrete feces and urine and the area where they eat food. The inventors assumed that this habit was a manifestation of cats recognizing the place where they excrete and the place where they eat separately, and they conducted research with the idea that if they could make cats recognize and learn that the place where feces and urine damage occurs is the eating place, the feces and urine damage could be reduced. As a result, it was revealed that when a fragrance compound similar to cat food was applied to the place where feces and urine damage occurs, the excretion behavior in the treated place could be suppressed immediately after the treatment. In particular, it was found that the excretion behavior in the treated place was strongly suppressed immediately after the treatment of sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds among the fragrance compounds similar to food, and the present invention was completed. The cat excretion inhibiting composition and cat excretion inhibiting method of the present invention are based on cats' distinguishing and recognizing the place where they excrete from the place where they eat, and learning about this, and are fundamentally different from repellents that use odors or ingredients that cats dislike to keep cats away. This will be explained in detail in the examples below, but it is also supported by the fact that the effects of the cat excretion inhibiting composition and cat excretion inhibiting method of the present invention continue even after the active ingredient has disappeared, while the repellent loses its repellent effect as the active ingredient disappears.

[0010] The feline excretion inhibiting composition of the present invention contains, as an active ingredient, one or more compounds selected from the group consisting of sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds. <Sulfur-containing compounds> The sulfur-containing compound in the present invention is also called an organic sulfur compound, and means an organic compound containing a sulfur atom. Although sulfur-containing compounds are generally recognized as compounds having an unpleasant odor, they are also known to have a strong and characteristic aroma at low concentrations, and are used as meat-like, particularly cooked meat-like, aroma compounds. The sulfur-containing compound in the present invention is preferably a compound having a molecular weight in the range of 50 to 250, more preferably a compound having one or two sulfur atoms in one molecule, and particularly preferably a sulfide compound or disulfide compound. Specific examples of compounds suitable as the sulfur-containing compound in the present invention include dimethyl sulfide, 2,4-dithiapentane, 3-(methylthio)propanal, dimethyl sulfone, furfuryl methyl disulfide, and difurfuryl disulfide.

[0011] <Saturated fatty acids> The saturated fatty acid in the present invention is a monovalent carboxylic acid of a hydrocarbon that does not have a double 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, coconut, palm oil, etc., and are known to be a flavor component unique to dairy products. In the present invention, the saturated fatty acid is preferably a compound having a boiling point in the range of 210 to 400° C., and among them, saturated fatty acids having 7 to 18 carbon atoms are preferred, and saturated fatty acids having 7 to 9 carbon atoms are more preferred. Specific examples of compounds suitable as saturated fatty acids in the present invention include heptanoic acid (carbon number: 7, boiling point: 223°C), octanoic acid (carbon number: 8, boiling point: 240°C), and nonanoic acid (carbon number: 9, boiling point: 254°C).

[0012] <Saturated aliphatic hydrocarbon compounds> The saturated aliphatic hydrocarbon compound in the present invention is a hydrocarbon compound that does not have a double bond or triple bond in the carbon chain and is saturated with hydrogen. Saturated aliphatic hydrocarbon compounds are known to be aroma components of bonito flakes. The saturated aliphatic hydrocarbon compound in the present invention is preferably a compound having a boiling point in the range of 210 to 320°C, and among them, a saturated aliphatic hydrocarbon compound having 12 to 18 carbon atoms is preferred, and a saturated aliphatic hydrocarbon compound having 12 to 14 carbon atoms is more preferred. Specific examples of compounds suitable as the saturated aliphatic hydrocarbon compound in the present invention include dodecane (carbon number 12, boiling point: 214 to 216°C), tridecane (carbon number 13, boiling point: 234°C), and tetradecane (carbon number 14, boiling point: 253 to 255°C).

[0013] The content of the active ingredient in the cat excretion inhibiting composition of the present invention is not particularly limited and may be appropriately set, but is preferably 0.5 ppb to 10 wt%, more preferably 0.5 ppm to 3 wt%, and even more preferably 0.001 to 2 wt% based on the total amount of the cat excretion inhibiting composition. If the content is less than 0.5 ppb, an excellent cat excretion inhibiting effect cannot be obtained, and if the content exceeds 10 wt%, not only will the cat excretion inhibiting effect not change significantly, but there is also a risk of it becoming an irritating odor to humans, which is undesirable.

[0014] <Preparation> The cat 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 may be appropriately set according to the mode of use. For example, it can be in the form of an oil solution, an emulsion, a wettable powder, a granule, a powder, a spray, an aerosol, a coating agent, a cleaning agent, a sheet agent, an injection agent, etc. Preferred formulation forms are 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, granules and powders are convenient because they can be easily applied by sprinkling them on horizontal surfaces where it is desired to suppress cat excretion, while spray preparations such as aerosol agents are preferred because they can be easily applied to vertical surfaces where it is desired to suppress cat excretion.

[0015] In preparing the liquid preparation of the cat excretion inhibiting composition of the present invention, surfactants such as nonionic, anionic, cationic, etc. can be blended as necessary. Specifically, for example, nonionic surfactants such as alkylaryl ethers, polyoxyethylated 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 ester salts, alkyl sulfonates, and alkylaryl sulfonates, and cationic surfactants such as alkyl ammonium halides can be exemplified. Among them, when the stock solution of the cat excretion inhibiting composition of the present invention is made into an aqueous solution, it is preferable to blend 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 inhibiting composition of the present invention may be blended with other known liquid carriers, gaseous carriers, solid carriers, and other formulation auxiliary agents. Examples of liquid carriers include aromatic or aliphatic hydrocarbons (xylene, toluene, alkylnaphthalene, phenylxylylethane, kerosene, diesel, 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. (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-methyl-pyrrolidone, 3-methoxy-N,N-dimethylpropionamide, etc.), alkylidene carbonates (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, fluorocarbon gas, alternative fluorocarbons (such as HFOs and HFCs), liquefied petroleum gas (LPG), dimethyl ether, nitrogen gas, and carbon dioxide gas. 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 bodies.

[0018] Other formulation adjuvants include adhesives, dispersants, solubilizing agents, and stabilizers, such as 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, further, if necessary, components such as rust inhibitors, preservatives, pH adjusters, and fragrances can be appropriately added. As these components, those commonly used in this field can be used, and specifically, examples of rust inhibitors include Carlen No. 955, No. 906, No. 954, No. 958, and No. 970 (all trademarks of Sanyo Chemical Industries, Ltd.), etc., preservatives include methyl paraoxybenzoate, ethyl paraoxybenzoate, propyl paraoxybenzoate, butyl paraoxybenzoate, isothiazolinone, sodium salicylate, sodium benzoate, phenoxyethanol, potassium sorbate, and sodium dehydroacetate, and 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, inorganic acids such as phosphoric acid, and their salts.

[0019] Regarding the case where the feline excretion inhibiting composition of the present invention is made into a granule or powder, for example, a liquid preparation 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 made into a granule or powder by supporting the liquid preparation on a porous solid carrier such as zeolite. The size of the porous solid carrier such as zeolite used can be, for example, about 0.1 to 10 mm in the form of a powder, sphere, or pellet, and among these, about 1 to 5 mm in the form of a sphere or pellet is preferred. These granules or powders can be scattered in areas where it is desired to inhibit cat excretion, or they can be stored in breathable bags or containers and placed or installed in areas where it is desired to inhibit cat excretion.

[0020] Regarding the case where the feline excretion inhibiting composition of the present invention is filled into an aerosol spray container to prepare an aerosol agent, a wide variety of known propellants can be used, such as butane gas, chlorofluorocarbon gas, alternative chlorofluorocarbons (HFO, HFC, etc.), liquefied petroleum gas (LPG), dimethyl ether, nitrogen gas, carbon dioxide gas, etc. In the feline excretion inhibiting composition of the present invention, the amount of propellant can be 10 to 95% by volume, particularly 30 to 90% by volume, of the total feline excretion inhibiting composition. When preparing the cat excretion inhibiting composition of the present invention as an aerosol preparation, methods commonly used in this field can be widely used. Among them, a representative method is to heat (30 to 50°C) one or more active ingredients selected from sulfur-containing compounds, saturated fatty acids, and saturated aliphatic hydrocarbon compounds as necessary to prepare a homogeneous solution, add rust inhibitors, preservatives, etc., and put the resulting stock solution into an aerosol spray container, fill it with a propellant, and make a product. The aerosol preparation of the cat excretion inhibiting composition of the present invention thus obtained is stable and can maintain a homogeneous state even under harsh conditions for a long period of time, and can be sprayed as fine particles with one touch when desired to treat the area where cat excretion is to be inhibited.

[0021] Regarding the case where the feline excretion inhibiting composition of the present invention is made into a spray preparation, for example, the composition can be used as a spray preparation by filling a spray container with a liquid preparation obtained by dissolving or dispersing one or more active ingredients selected from a sulfur-containing compound, a saturated fatty acid, and a saturated aliphatic hydrocarbon compound in water with a nonionic surfactant. The spray container may be one that can be easily filled with a liquid preparation and has a spray function, but in consideration of versatility and high spray accuracy, a trigger-type spray container or a mist-type spray container is preferred, and a trigger-type spray container is particularly preferred. This trigger-type spray container is a container body that is filled with the contents and has a pistol-shaped trigger-type spray device attached to the mouth, and can operate the spray at atmospheric pressure, making it a highly versatile spray container. The trigger-type spray container here includes all trigger-type spray containers that have been partially improved to improve the spray function.

[0022] The cat excretion inhibiting composition of the present invention can inhibit cat excretion by treating an area where cat feces and urine are not desired, whether indoors or outdoors. This effect is achieved by cats recognizing the area treated with the cat excretion inhibiting composition of the present invention as an unsuitable excretion area. Therefore, even if the concentration of the active ingredient in the cat excretion inhibiting composition of the present invention decreases, the excretion inhibiting effect can be obtained for a long period of time, which is fundamentally different from general cat repellents. The cat excretion suppression 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. To obtain a more sufficient effect, 0.02 μg to 5 g / m 2 , more preferably 0.02 mg to 3 g / m 2 , and more preferably 0.01 to 1 g / m 2 can be applied. 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, all parts are by weight.

[0024] <Test 1 to confirm the effect of suppressing excretion in cats> (1) Preparation of test samples A test specimen of Example 1 was obtained by dissolving 1 part by weight of dimethyl sulfide in 10 parts by weight of isopropyl myristate, and supporting this evenly on 89 parts by weight of zeolite having a particle size of 2 to 3 mm. In Examples 2 and 3, the compositions are shown in Table 1 below, and the test specimens were obtained in the same manner as in Example 1. "Fragrance composition A," which is the active ingredient in Example 3, is a blended fragrance containing dimethyl sulfide, octanoic acid, tridecane, 2,4-dithiapentane, 3-(methylthio)propanal, dimethyl sulfone, furfuryl methyl disulfide, and difurfuryl disulfide. In Table 1, "IPM" stands for isopropyl myristate.

[0025] [Table 1]

[0026] (2) Test method for confirming the effect of suppressing excretion in cats A place where stray cats repeatedly defecate and urinate (approximately 1m 2 ) Test specimens (Examples 1 to 3) were applied at 35 g / m 2 The area was sprayed evenly so that the area was 2 The day when the test samples (Examples 1 to 3) were sprayed was set as the test start date, and the presence or absence of feces was confirmed after each elapsed time. If feces were found, they were removed and the cumulative number (pieces) 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 four weeks after the start of the test, whereas in the test sample of Example 3 containing multiple active ingredients of the present invention, no cat feces were found for four weeks from the start of the test. Also, in the test samples of Examples 1 and 2 containing only one active ingredient of the present invention, the number of feces was 5 and 2, respectively, during the four-week period from the start of the test, which revealed that the number of feces was suppressed by about 10 to 30% compared to the untreated area.

[0028] <Test to confirm the effect of suppressing excretion in cats 2> In the above "Test 1 to confirm the effect of suppressing excretion in cats," the test sample of Example 3, which demonstrated an extremely excellent effect of suppressing excretion in cats, was used to conduct a test to compare the cat excretion suppression effect with that of the active ingredients of commercially available cat repellents. (1) Preparation of test samples The test sample of Example 3 in the above "Test 1 for confirming excretion suppression effect in cats" was used. For Comparative Examples 1 and 2, the test specimens were obtained in the same manner as in Example 1 of the above-mentioned "Test 1 to confirm the effect of suppressing excretion in cats" with the formulations shown in Table 2 below. The active ingredients of Comparative Examples 1 and 2, plant essential oil B and methyl salicylate, are active ingredients of commercially available cat repellents, and plant essential oil B is an essential oil consisting of a mixture of ingredients extracted from herbs (thyme, clove, perilla, etc.). In Table 2, "IPM" stands for isopropyl myristate.

[0029] [Table 2]

[0030] (2) Test method for confirming the effect of suppressing excretion in cats The cumulative number of feces (pieces) was counted in the same manner as in the above-mentioned "Test 1 for confirming the effect of suppressing excretion in cats." The results are shown in Figure 2.

[0031] As shown in FIG. 2, in the untreated area where nothing was sprayed, the cumulative number of feces was 18 five weeks after the start of the test, whereas in the test sample of Example 3 containing multiple active ingredients of the present invention, only one cat feces was produced over a period of five weeks from the start of the test. As in the above-mentioned "Test 1 to confirm the effect of suppressing excretion in cats," it was confirmed that the test sample exhibits an extremely excellent effect of suppressing excretion in cats. Since the excretion suppression effect was obtained for a long period of 5 weeks, it is believed that the cat's excretion suppression effect was exerted by the cat recognizing and learning that the treated area is not an excretion area. In contrast, the test samples of Comparative Examples 1 and 2, which contain plant essential oil B and methyl salicylate, which are active ingredients in commercially available cat repellents, showed a cat excretion suppression effect compared to the untreated group for two weeks from the start of the test, but no suppression effect was obtained thereafter, and as a result, the cumulative number of feces five weeks after the start of the test was the same as the untreated group at 18 or even higher at 22. This is thought to be because the cat repellent ingredients of the test samples of Comparative Examples 1 and 2 volatilized two weeks after the start of the test, and the repellent effect was no longer obtained. The results of Example 3, which is a specific example of the present invention, and Comparative Examples 1 and 2 support the idea that the cat excretion inhibitor composition of the present invention is based on cats' ability to distinguish and recognize the places where they excrete and the places where they eat, and that this ability is learned, and is fundamentally different from repellents that use odors or ingredients that cats dislike to keep cats away.

[0032] <Test to confirm the effect of suppressing excretion in cats 3> (1) Preparation of test samples A test specimen of Example 4 was obtained by dissolving 1 part by weight of furfuryl methyl disulfide in 10 parts by weight of isopropyl myristate, and supporting this uniformly on 89 parts by weight of zeolite having a particle size of 2 to 3 mm. A test sample of Example 5 was obtained in the same manner as the test sample of Example 4, except that tridecane was used instead of furfurylmethyl disulfide. In Table 3, "IPM" stands for isopropyl myristate.

[0033] [Table 3]

[0034] (2) Test method for confirming the effect of suppressing excretion in cats The cumulative number of feces (pieces) was counted in the same manner as in the above-mentioned "Test 1 for confirming the effect of suppressing excretion in cats." 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 pieces 4 weeks after the start of the test, whereas in the test sample of Example 4 containing only one active ingredient of the present invention, no cat feces were found for 4 weeks from the start of the test. Also, in the test sample of Example 5 containing only one active ingredient of the present invention, the number of feces was 1 piece in the period of 3 weeks from the start of the test, and 3 pieces in the period of 4 weeks, which shows that the feces are significantly suppressed compared to the untreated area.

[0036] <Testing to confirm accidental ingestion of cat excretion suppressant composition> (1) Preparation of test samples The test specimen of Example 3 in the above "Test 1 for confirming the effect of suppressing excretion in cats," fragrance composition A, and commercially available cat food were used. Fragrance composition A was used by soaking absorbent cotton without diluting it. (2) Test method The test sample of Example 3, fragrance composition A (undiluted and soaked into absorbent cotton) and commercially available cat food were scattered / placed in areas within the territories of stray cats where feces and urine were repeatedly released and in areas other than the excretion areas, and the behavior of the cats was observed (observation period: August to September 2019, 1 hour between 10:00 and 17:00, observations 6 times) to confirm whether the cats were eating or urinating (including whether they licked the food). (3) Results At all observation times, eating behavior of the commercially available cat food was confirmed both in the excretion area and in areas other than the excretion area, but eating behavior of the test sample of Example 3 and fragrance composition A was not confirmed both in the excretion area and in areas other than the excretion area. From these results, it was confirmed that the feline excretion inhibiting composition of the present invention is not accidentally ingested by cats.

[0037] <Test 4 to confirm the effect of suppressing excretion in cats> (1) Preparation of test samples The test sample of Example 3 in the above "Test 1 for confirming excretion suppression effect in cats" was used. (2) Test method The stray cats that make up groups A and B were individually identified, and an area P (100 m2) was identified within the territory of group A where the stray cats that make up group A repeatedly defecate and urinate. 2A park) and an area Q (200m) where stray cats that make up group B repeatedly defecate and urinate within group B's territory. 2 The behavior of each individual member of groups A and B in areas P and Q was observed (October to December 2019, 16:00 to 18:00, six observations). Three members of group A (referred to as A-1, A-2, and A-3) were observed in area P, and five members of group B (referred to as B-1, B-2, B-3, B-4, and B-5) were observed in area Q. The number of feces in areas P and Q where excretion behavior was observed was 26 and 10, respectively. After removing the feces confirmed in areas P and Q, the excretion site p (approximately 33 m) where the excretion behavior of individual A-1 in area P was confirmed was 2 ) and excretion site q (approximately 66 m) where the excretion behavior of two individuals, B-1 and B-2, was confirmed in area Q. 2 ) and the test specimen of Example 3 was 35 g / m 2 It was spread evenly so that Six weeks after the spraying treatment, the presence or absence of feces was checked at each excretion site.

[0038] (3) Results Six weeks after spraying, no feces were found at all in the excretion sites p and q treated with the test sample of Example 3, nor in any other locations within area P than excretion site p (untreated area), nor in any other locations within area Q than excretion site q (untreated area). These results demonstrate that an excellent excretion inhibitory effect can be obtained not only at the excretion locations p and q treated with the test sample of Example 3, but also throughout the entire areas P and Q, including locations that were not treated with the test sample of Example 3. Although excretion sites p and q are locations where the excretion behavior of some individuals (A-1, B-1, B-2) in groups A and B was confirmed, it was confirmed that a long-term excretion suppression effect was obtained not only for these individuals (A-1, B-1, B-2) but also for the other individuals in groups A and B (A-2, A-3, B-3, B-4, B-5). It has become clear that by simply treating a portion of an area where cat excretion has been confirmed with the cat excretion inhibiting composition of the present invention, the cat excretion inhibiting effect can be obtained for a long period of time not only in the treated area but also over a wide area surrounding it. [Industrial Applicability]

[0039] By treating an area with the cat excretion inhibiting composition of the present invention, it is possible to inhibit cat excretion not only in the treated area but also over a wide area around the treated area. Moreover, the present invention achieves the excretion inhibiting effect by making the cat recognize that the area treated with the cat excretion inhibiting composition is not an excretion area, and therefore, even if the concentration of the active ingredient in the composition decreases, the excretion inhibiting effect can be maintained for a long period of time, which is useful. The present invention can make all cats in a group recognize that the area treated with the cat excretion suppressing composition is not an excretion area, thereby achieving a significant excretion suppressing effect. Furthermore, the feline excretion inhibiting composition of the present invention is also highly safe since it will not be accidentally eaten or ingested by cats, and can be used safely, for example, when training indoor cats to use the litter box.
