FeLV (Feline Leukemia Virus) is spread from cat to cat by bodily secretions. Saliva and blood can spread the virus and cat fights are a cats greatest risk of catching this cancer causing disease. The virus can spread from mother to kitten, even in the womb. The FeLV blood test is an effective way to screen any new cat or kitten of this deadly disease before they are introduced to your home. Testing and vaccination have definitely decreased the incidence of FeLV infection and disease, but the outdoor feral cat population will always be a source FeLV. If your pet spends time outdoors they should be vaccinated. Having them spayed or neutered will decrease their chance of being in a cat fight and will also help protect them.
