One-year-old cats that have not been vaccinated need to be vaccinated with 3 doses of combined vaccine and 1 shot of rabies. Before vaccination, the cat must be in a healthy state and must not have coughing, runny nose, frequent sneezing, vomiting, diarrhea, etc. Fever and other abnormal conditions. Cats may experience loss of appetite, poor spirits, etc. after being vaccinated, which usually subside after 1-2 days. If there is no improvement for a long time, you need to consult a pet doctor.

Situations in which cats cannot be vaccinated:

1. Generally, cats cannot be vaccinated when they are less than six weeks old. The immune system of most kittens is strictly protected by maternal antibodies in colostrum. Even if they are vaccinated, the effect of the vaccine will be neutralized by the antibodies in colostrum and cannot stimulate the immune system to produce antibodies.

2. Cats with poor physical fitness and malnutrition cannot be vaccinated.

3. Cats cannot be vaccinated when they are sick. Vaccination at this time may aggravate the condition due to vaccine reactions.
