The kittens are vaccinated by us at the age of 8 and 12 weeks against cat's flu and Panleukopenia. Then the new owner can fresh up this vaccination every year. Your vet will advise you. At every vet visit, the vaccination booklet that we deliver with the kitten shall be brought along. Leukemia vaccination is recommended for cats that walk outside and can be bitten by other cats. For cats that should travel abroad, additional rabies vaccination is necessary.
