Reasons for cats vomiting out complete cat food:

1. The cat ate too much. When cat food enters the stomach, it will absorb water and expand. If the cat eats too much cat food at one time and drinks a lot of water, the cat food will fill the entire stomach, and the cat will vomit it out if it cannot digest it completely.

2. The cat is spitting out hair balls. If you can see cat hair in the cat food, it means that the hair has accumulated in the intestines and stomach and has been spit out along with the cat food.

3. Cat’s gastrointestinal discomfort. Sometimes cats eat cold, spoiled, or difficult-to-digest food, which can cause gastrointestinal discomfort, such as swallowing wool, plastic bags, etc.

4. The cat has enteritis. If your cat not only vomits but is also accompanied by diarrhea, loss of appetite and other symptoms, the cat may have enteritis.

5. The cat has an infectious disease. If your cat shows symptoms of enteritis and even has a fever, it is most likely infected with feline distemper.
