Young kittens are protected from some infectious diseases by antibodies given to them by their mothers. This protection wears off between seven and nine weeks of age.
Vaccination will not be of benefit in kittens until the protection from their mothers has waned. We therefore recommend kittens are given their primary vaccination course at nine and twelve weeks of age. If your kitten is older or if you have acquired an adult cat with no previous vaccination history this primary vaccination course can commence at any age.
Rabies vaccination and the pet passport scheme can commence from three months of age.
