Adult cats should be vaccinated against rabies and infectious diseases every year, which can not only enhance the cat’s resistance but also prevent viral infections. The owner should remember the time of each vaccination for the cat, inject the cat regularly, and do not bathe the cat for a few days before and after the injection, so as not to affect the efficacy of the medicine. If the cat develops vomiting or diarrhea after receiving the vaccine, the owner should seek medical advice promptly. The hospital conducts examination and treatment.
