Feline leukemia virus (FeLV) is a retrovirus found in cats everywhere in the world. While FeLV prevalence has decreased over the last few decades, primarily due to improvements in testing and vaccination, there are still millions of infected cats. Transmission of the virus occurs mainly via friendly contact, such as mutual grooming. Fortunately, the virus does not contaminate the environment as it is does not survive more than minutes outside the host. Young kittens are most at risk of infection. The most common clinical problems associated with FeLV infection are immunosuppression (with secondary infections), anemia, and lymphoma. Fortunately, effective vaccines exist against FeLV for cats at risk of infection. [SL]
