Feline leukemia virus infection is a viral infection that is spread between cats by prolonged contact with saliva or nasal secretions. Infection most commonly occurs in outdoor male cats between 1 to 6 years of age. Approximately 30% of exposed cats are persistently viremic (and remain infected), 30% are transiently viremic (infected with the virus and then cure themselves of the infection), and the remaining 40% of cats are latently infected and test negative on blood testing (the infection resides somewhere in the body such as the spleen, lymph nodes, or bone marrow but not in the blood).

Similar to infection with the FIV virus, the most typical signs seen in infected FeLV positive cats are chronic disease, such as diarrhea, skin infections, and dental disease. Cancerous tumors may also occur. Any clinical signs (such as seizures) can occur as the signs that are seen depend upon the specific body tissue infected by the virus. Cats who persistently test positive on the blood tests for the virus will usually be infected for life.
