How often does a cat need FeLV vaccine?

Kittens should begin their vaccination series at 6-8 weeks of age and these vaccines should be boostered every 3-4 weeks until at least 14 weeks of age, when adult immunity takes over. Depending on the vaccine, your pet should then be boostered annually or every 3 years in the case of rabies.

How do I protect my cat from FIV?

The only sure way to protect cats is to prevent their exposure to the virus. Cat bites are the major means by which infection is transmitted, so keeping cats indoors, away from potentially infected cats that might bite them, markedly reduces their likelihood of contracting FIV infection.
