Common causes of cat vomiting:

1. In most cases, cats vomit due to hair vomiting. Cats have the habit of licking their fur to clean themselves. During the licking process, some cat hair will inevitably be swallowed into the cat's belly. When the cat hair accumulates to a certain amount, the cat will excrete the cat hair through vomiting.

2. Cat gastrointestinal sensitivity is also one of the main causes of vomiting in cats. When cats eat food that is not suitable for their appetite or eat too fast, they will have symptoms of vomiting or even diarrhea.

3. If the cat accidentally eats some food that is harmful to the cat, it will cause vomiting. Green plants at home such as daffodils, azaleas, oleander, etc. can cause poisoning in cats.

4. Tension and pressure. Cats are very sensitive animals. When they feel nervous and stressed, they will have a stress reaction and vomit easily.

5. The disease causes vomiting. This condition usually occurs in older cats. Some internal diseases can cause nausea and vomiting in cats. In this case, cats will become inactive and unwilling to eat, and their drinking and excretion will be abnormal.
