Description

Technical Field

[0001] The present invention relates to the field of pet nutritional supplements, and particularly to a freeze-dried formula, granules and a preparation method of a hair-removing and hair-discharging nutritional supplement for cats. Background Art

[0002] As one of the common pets, cats often have the phenomenon of hair accumulation in daily life. Especially for long-haired cats and elderly cats, they often suffer from gastrointestinal discomfort due to excessive hair swallowing, and in severe cases, it may even cause hair blockage, retching, loss of appetite and other problems. To solve this problem, there are already some hair-removing and hair-discharging products for cats on the market, which mainly help cats effectively discharge the hair in the body by providing dietary fiber and lubricating the intestinal tract. However, the existing hair-removing and hair-discharging products still have some deficiencies: Poor palatability: Most of the existing products may focus on drug or health care functions in the formula, resulting in a low acceptance rate of cats. Many cats refuse to eat due to dislike of the taste or texture of the products, thus affecting the effect.

[0003] Single ingredient or high irritation: Among the existing hair-removing and hair-discharging products for cats, some use chemical additives or excessive drug ingredients, which may cause greater irritation to the gastrointestinal tract of cats and may affect health if eaten for a long time.

[0004] Insufficient lasting effect: The effects of existing products are usually not significant or persistent enough. Cats may still have discomfort reactions such as vomiting or diarrhea during hair discharge, affecting the daily life of pets.

[0005] Therefore, how to design a product that can not only effectively help cats discharge hair, but also ensure high palatability, mild hair-discharging effect and good effect after long-term use has become a technical problem to be solved urgently in the field of pet food.

[0006] The present invention provides a freeze-dried hair-removing and hair-discharging nutritional supplement for cats and its preparation method, which adopts a multi-layer particle structure and a freeze-drying process to ensure the stability and palatability of active ingredients, can not only effectively promote hair discharge, but also provide nutritional support, and avoid irritation to the gastrointestinal tract of cats.
