Ragdoll cats need to be vaccinated once a year after they reach adulthood. If they are kittens, they need to receive the first vaccine at two months, then the second vaccine every 21 days, and then the second vaccine every 21 days. For the third dose of vaccine, the cat needs to be dewormed one week before the vaccine. Newly picked-up kittens cannot be vaccinated immediately. You must wait until the cat is familiar with the environment before vaccination, otherwise it will easily cause the cat to get sick.
