Feline Leukemia Virus (FeLV) - Symptoms, Treatment & Prevention
Understand FeLV transmission, symptoms, and prevention. Vaccination can help prevent this serious virus.
What is Feline Leukemia Virus (FeLV)?
Feline Leukemia Virus (FeLV) is a serious virus affecting a cat's blood cell production. It progresses faster than FIV. Vaccination can prevent infection, and early diagnosis with proper treatment can extend lifespan.

FeLV Transmission
FeLV spreads through saliva, nasal secretions, urine, and feces. Transmission occurs through contact, grooming, and sharing food bowls. Vertical transmission from mother to kitten is possible, and indoor cats are also at risk.
FeLV Symptoms
- Early: Fever, lethargy, anorexia, enlarged lymph nodes
- Middle: Anemia (pale gums), oral disease, chronic infections
- Late: Malignant tumors, neurological disease, severe immunosuppression
Diagnosis & Treatment
FeLV is diagnosed with blood tests (ELISA or qPCR). Early infection may test negative, so retesting after 3 months is recommended. No approved specific antiviral treatment exists; symptomatic management (anemia, secondary infections, etc.) is the primary approach.
FeLV Prevention
Regular vaccination prevents FeLV infection. Indoor cats should be vaccinated if exposed to outdoor cats. New cats should be isolated and tested negative before co-habitation.
