Feline leukemia virus is a retrovirus that infects cats. FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved.
Cats with feline leukemia can live months to years depending on infection type and care. Heres what shapes their prognosis and how to support them.
Our findings from this prospective study of adopted FeLV-infected cats revealed an overall median survival of 2.8 years, with high positive cats having the shortest median survival of 1.4 years and only 2/90 cats still known to be alive at more than 7 years.
If we want to mention some figures, we can say that about 25% of cats with feline leukemia die within 1 year after being diagnosed. But 75% survive for 1 to 3 years with the virus active in their bodies. Learn how long cats live with feline leukemia, including symptoms, progression, care tips, and how to improve your FeLV-positive cats quality of life. How Long Do Cats with Feline Leukemia Typically Survive? For adult cats, survival after an FeLV diagnosis typically falls somewhere between 2 and 6 years, with a median of around 2.5 years according to Cornell Universitys Feline Health Center. Survival Rate: According to a recent study published in a veterinary journal, the survival rate for cats with feline leukemia is highly variable. Some cats may only live a few months after diagnosis, while others can live for several years.

Feline leukemia virus (FeLV) is one of the most common infectious causes of disease of cats globally. Infection with FeLV can cause a variety of clinical signs, impacting a cat's longevity and quality of life.
