It is not recommended to vaccinate cats when they are 45 days old. Vaccination too early may cause adverse reactions. It is generally recommended to vaccinate cats around 2 months old. Cats need to receive 3 doses of infectious disease vaccines in the first year, mainly to prevent viral infectious diseases such as feline distemper. In addition, one dose of rabies vaccine is also required. The first vaccination age of this vaccine is 3 months of age, which can be used to prevent zoonotic rabies.

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. Cats should be observed carefully after being vaccinated. Cats may experience fever, poor mental health, loss of appetite, lethargy, etc. after being vaccinated. These are normal reactions and will usually recover on their own in 1-3 days. If it exceeds three days, you should contact your doctor immediately for consultation.

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.
