It may be the effect of the vaccine that causes the cat to vomit. To be on the safe side, it is recommended to consult a pet doctor who vaccinates the cat. General vaccines are divided into attenuated vaccines and inactivated vaccines. The commonly used Interwin Cat Triplex is an attenuated vaccine, which means that a small amount of virus will enter the cat's body to allow the cat to develop its own resistance. Due to the invasion of the virus, cats will develop low fever, vomiting, diarrhea, loss of appetite, listlessness and other symptoms within 1 to 2 days after vaccination. These are all normal phenomena.

Due to the side effects of the vaccine, the cat needs to be in good health before vaccination. If the cat’s resistance is poor, problems will easily occur after vaccination. As is often said about vomiting, give the cat pet probiotics first and observe it for two or three days to see if the cat's vomiting symptoms improve. If vomiting persists for a week, you need to take the cat to a pet hospital for examination and treatment.

After a cat is vaccinated, because its resistance is relatively weak, it is best to bathe the cat after a week or half a month to prevent the cat from getting cold, frightened and sick. Also do not take your cat for a walk outside to prevent the cat from being infected with bacteria, viruses, or catching a cold.
