Precautions for cat vaccination:

1. Cats must be vaccinated after they are 60 days old. When the cat is not weaned, it will pass through the mother cat’s milk. To obtain maternal antibodies, after the cat is weaned for about one and a half months, the cat should be given a time to adapt. Only when it has a certain level of resistance can it be vaccinated.

2. Do not vaccinate the cat immediately when you first bring it home. It takes one to two weeks to adapt to the new environment before being vaccinated. Cats can easily become stressed after a change of environment, and the owner is not sure whether the cat has any disease, so they need to observe it for a period of time.

3. Cats can only be vaccinated when they are completely healthy. Vaccines are composed of attenuated viruses. After a cat is vaccinated, the attenuated virus will stimulate the cat to produce antibodies. If the cat is vaccinated in an unhealthy state, the attenuated virus in the vaccine can easily cause the cat to become sick.
