Cats allergic to vaccines often show enlargement of the head, swollen eyelids, excessive tearing, and sometimes a rash. In addition, some cats may also experience abnormalities such as fever and loss of appetite, which will generally subside two to three days after vaccination. If the symptoms do not subside for a long time, it is recommended to take them to the pet hospital for relevant examination and treatment in time.

What should be paid attention to when vaccinating kittens:

1. Vaccination is not recommended before the age of two months. Because kittens before two months of age are protected by maternal antibodies, if vaccinated at this time, it will easily cause the vaccine to become ineffective. Therefore, the level of maternal antibodies in the kittens should be reduced before vaccination.

2. It is generally recommended to inject rabies vaccine when kittens are three months old.

3. Kittens can only be vaccinated if they are in good health. Do not take a bath or go out for one week after vaccination to avoid contracting germs and getting sick.
