Reasons for cats vomiting and not eating:

1. There are parasites in cats that live in the gastrointestinal tract and can easily cause vomiting and diarrhea.

2. Cats may vomit after eating unclean or toxic substances, which may affect liver and kidney function in severe cases.

3. Cats may suffer from other diseases, such as feline distemper, gastroenteritis, pancreatitis, etc. Cat gastroenteritis can be treated with infusion or injection. Injections and infusions are mainly antibacterial and anti-inflammatory, regulating the balance of gastrointestinal flora and enhancing the function of the gastrointestinal system. The general treatment time for cats with gastroenteritis is 3-5 days. After recovery, you can eat canned intestinal food, probiotics or intestinal cat food for conditioning for a period of time to help the intestinal tract recover.

4. Cats eat a lot of hair and suffer from hairball syndrome. This is the most common cause of vomiting in cats, and it affects both long-haired and short-haired cats, as well as dogs and rabbits. The typical symptom of hairball disease is vomiting about 1 to 3 times a week. The vomited things are strip-shaped hair balls. If the cat is usually fed grass, there will also be fragments of crude fiber.

5. Cats eat too quickly, or eat cold food, rotten food, or food with strong taste by mistake.
