What Age for the First Shots for Kittens? Your kitten will probably need her first shots at about 6 weeks old. As a responsible pet owner, you want to protect your precious kitten from disease. While newborn kittens can't handle vaccines, Fluffy will probably be ready for her first series of shots at about 6 weeks old.
Some veterinarians may recommend a kitten be vaccinated at the age of 9 weeks and then one or two more times for the next two or three weeks, until the cat is 13 weeks old. A booster shot of the vaccine is recommended every year by its manufacturers.
