Under normal circumstances, cats can be vaccinated 45 days after birth. Kittens need to be vaccinated for the first time with three doses of combined vaccine and one shot of rabies vaccine. One shot of the combined vaccine is given every 21 days. After receiving the combined vaccine, the rabies vaccine is given about a week later. Cats should be vaccinated with rabies vaccine after they are 3 months old. .
But vaccination must be done when the cat is in good health. If the cat is vaccinated when it is in poor health, It can easily cause disease or cause adverse effects. After the cat is vaccinated, stay with the cat in the hospital for observation for 30 minutes, so that if the cat develops allergies, it can be desensitized in time.
