I recommend that kittens start their shots at 6-8 weeks of age, and continue every 3-4 weeks until after they are 16 weeks of age. If Calypso has never received vaccinations, then she would need one set now and a booster in 3-4 weeks. When to spay a cat depends on the individual preference of the veterinarian, I recommend doing this at 4-5 months of age since cats can come into heat as early as 5 months old.

    Vaccines are usually started at 8 weeks of age for kittens and repeated eery 4 weeks untils 4 months old. Usually they are fixed at 6 months of age. It is best to have to vaccines completed prior to surgery so they are not at risk to catch any disease while staying at the hospital for the surgery
