Feline Leukemia Virus (FeLV) is a virus that attacks the immune system of a cat. It’s an immunosuppressive virus — not cancer — that can reduce life expectancy, though many affected cats still live long and fulfilling lives.
Our FeLV+ cats are healthy, not sickly — with proper care, they live happy lives and bring just as much joy as any other cat.
Is FeLV Contagious?
Only to other cats. The virus is spread cat-to-cat through saliva, urine, blood, and from mother to kitten. FeLV+ cats should only live with other FeLV+ cats, and indoor-only housing is strongly recommended. The virus does not infect other species and does not survive long outside the body.
How Is FeLV Diagnosed?
Diagnosis is usually done with an ELISA snap test, often combined with an FIV test. Cats over one year who test negative typically stay negative thanks to natural age-related resistance.
Are FeLV+ Cats Available for Adoption Sickly?
No. Our FeLV+ cats are just as healthy as any other cat available for adoption. They do carry an elevated risk of illness, which is why they need quality nutrition, regular vet visits, a low-stress environment, and prompt medical attention when needed.
Do FeLV+ Cats Need Special Medication or Care?
Not while they are healthy. Some vets recommend antiviral medications, though effectiveness remains debated. If they do become sick, they may deteriorate quickly due to their compromised immune system, so early attention is important.
What Medical Issues Should I Look For Post-Adoption?
Watch for fever, sneezing, nasal discharge, labored breathing, and lethargy. If your cat hasn’t eaten in 24 hours, try offering something highly palatable like baby food or scrambled eggs, and contact your vet if it continues.
