There are many causes of vomiting in cats, and different illnesses require different drug treatments. Common drugs include: 1. Anthelmintic drugs to treat internal parasites in cats. 2. Probiotics that regulate the cat’s gastrointestinal tract. 3. Hair removal cream that helps remove hair balls. 4. Drugs to treat cat food poisoning.

What to do if a cat vomits:

1. If the cat vomits after just eating normal cat food, you need to observe whether there is a lot of hair in the vomit. If there is a lot of hair in the vomit, you need to feed the cat hair removal cream to help eliminate the hair balls.

2. If the cat is infected with internal parasites, it is recommended to take the cat to a pet hospital for a fecal examination. After confirming the type of parasite infected, deworming drugs can be used accordingly.

3. If the cat is not fully vaccinated, it may be caused by feline distemper infection. It is recommended to send the cat to the doctor in time for infectious disease screening.

4. If the cat vomits after changing food, you can feed an appropriate amount of probiotics to regulate the gastrointestinal tract. Probiotics mainly mediate intestinal flora and improve intestinal function.
