Pet's info: Cat | Domestic Mediumhair | Male | neutered | 2 months and 19 days old | 2.5 lbs
My new kitten has had 3 FVRCP shots already and the shelter said to ask my vet if he needs another booster shot? He is 3 months old. The shelter told me that every vet has a different preference as to whether or not he’d need another booster shot. Also, how much would a consult be with this booster shot? Thank you!

Vaccines should be given at 8, 12 and 16 weeks of age. We do it that way because of interference with maternal antibodies. Maternal antibodies counteract the vaccines. Kittens get some antibodies against diseases from their mom's milk but we are not quite sure exactly when those antibodies go away. In some kittens they may not have received any antibodies from mom (ie: they were hand raised) or they may have good immunity. No way to tell. We do know that by 16 weeks of age the antibodies have waned completely so that is why we stop there. I'm not sure how Cheerio's shots got off timing - he should not have had 3 FVRCP vaccines already. That was definitely overkill. If he did have good maternal antibodies those would have counteracted the vaccines. So, I suggest he get one at 12 week and another at 16 weeks. You need to contact VETCO clinics for information on when the vaccine clinics will be in your area (Petco stores) and I believe the cost is on the website. When you take him to the clinic be sure he is in a carrier as there will be LOTS of dogs around. Take all his vaccine history with you as well.
