Causes of cats vomiting after eating:

1. Food change reaction
Changing the cat’s food will cause it to become uncomfortable and may cause vomiting. Don't change the food suddenly in one day, but do it step by step. You can mix the original cat food with the new cat food and let it adapt slowly.
2. Gastrointestinal discomfort
When a cat eats too much miscellaneous food, or eats too fast, it will cause gastrointestinal discomfort and vomiting. The owner needs to control the type of feeding, feed the cat regularly, and maintain a regular diet.
3. Cold

If the cat has a severe cold, intestinal peristalsis will decrease, and vomiting will also occur. The cat should be fasted for 4 hours and then fed light liquid food.
4. Parasites
When a cat is infected with parasites and irritates the gastrointestinal tract, it will cause vomiting. Parasites usually appear in the vomit, and cats need to be dewormed regularly.
5. Hair vomiting
If a cat has accumulated a lot of cat hair in its intestines and stomach for a long time, it will vomit it out. Obvious cat hair will be seen in the vomit. The owner can usually feed the cat hair removal cream or cat hair. Grass helps hair discharge.
