Three major reasons why cats vomit:

1. In most cases, cats vomit due to hair vomiting. Cats have the habit of licking their hair 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 expel the cat hair through vomiting. Vomiting The symptoms are usually thick strips of hair or cat hair accompanied by mucus. This phenomenon is called "vomiting hair balls" and is a means for cats to self-regulate their gastrointestinal tract. If the cat accidentally ingests a small amount of foreign objects, such as thread, a small amount of plastic, etc., it can also expel the foreign objects from the body through this method.

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. If you change cat food to your cat, you should pay attention to changing it gradually and gradually. If the cat particularly likes something, the amount should be controlled to avoid making the cat feel uncomfortable.

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. Cats with food poisoning will have difficulty breathing, nausea, vomiting, and decreased blood pressure. It is recommended to seek medical treatment as soon as possible. In addition to providing cat grass for cats to digest hair balls at home, owners should first confirm whether they are toxic to cats before planting green plants.
