When should my kitten get their first vaccines and be fixed?
Starting vaccines depends on the age the kittens left their mother. Kittens that were orphaned young and no longer have the antibodies from mom's milk may be vaccinated as early as six weeks, while kittens that were with mom may be vaccinated later at 8-10 weeks of age. There is then a series of vaccines that will be given 3-4 times over a period of every 4 weeks or so to finish the course. Rabies vaccines, which must be given by a vet, are usually given at around 5-6 months of age.
Most kittens are spayed/neutered at around 5-6 months of age, before they reach sexual maturity, however some shelters and veterinary clinics do spay and neutered kittens once they've reached a certain size/weight, rather than age. Checking with your vet to see their policy is best.
