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.
Kittens continue to grow and play, becoming bolder and more confident every day. A kitten at this age is equivalent to a child aged 3-5. (See our kitten age chart for more comparisons.) At twelve weeks a kitten should receive its second set of vaccinations for feline enteritis and cat 'flu. Reputable breeders won't sell Siamese kittens until they have had this second round of vaccines.
