Leukemia Vaccination for Cats
All cats that go outside should receive the Feline Leukemia vaccine (FELV).  Feline Leukemia is a virus that causes cancer.  Vaccinating to prevent a type of cancer is a great thing.  The disease is transmitted by hissing and spitting.  If a positive cat hisses at another cat that does not have the disease and the spit gets in the healthy cat's eyes or mouth, the disease will be transmitted.  We all know how strange cats greet each other so this is a great way for the virus to get around. 
 
This virus cannot be given to people or dogs.  You, your children and your canine friends are safe. Only cats are at risk.  Cats that are at risk for this type of exposure should receive two FELV vaccines 3-4 weeks apart.  We recommend this vaccine be boosted annually.
 
This vaccine also has it's own set of health risks.  We do not recommend vaccinating indoor cats with no risk of saliva contact.
