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.
For kittens, an initial dose as early as 8 weeks of age is recommended, depending on product; a second dose should be administered three to four weeks later. For adults and kittens over 16 weeks of age receiving vaccination for the first time, two doses, three to four weeks apart are recommended.
