Feline Leukemia Virus (FeLV): Veterinary Guidance for Cat Owners

Feline leukemia virus (FeLV) is a serious, contagious viral infection that affects a cat’s immune system. While some cats may show few symptoms at first, FeLV can lead to life-threatening illness if left untreated.

How FeLV Spreads

FeLV is transmitted primarily through saliva, nasal secretions, and mutual grooming. It can also spread via shared food bowls, litter boxes, or bite wounds. Cats who go outdoors or live with infected cats are at higher risk.

Symptoms of FeLV

• Persistent fever or lethargy
• Weight loss or poor appetite
• Pale gums or anemia
• Recurrent infections (respiratory, urinary, skin)
• Enlarged lymph nodes

Some cats may carry the virus without showing symptoms for months, which is why regular testing is essential, especially for new cats, kittens, or those exposed to other cats.

Prevention and Management

• Vaccination: A FeLV vaccine is available and recommended for kittens and high-risk cats.
• Testing: Routine testing identifies infected cats early and helps prevent transmission.
• Indoor lifestyle: Keeping cats indoors reduces contact with infected cats.
• Supportive care: While there’s no cure, supportive treatment can improve quality of life and manage secondary infections.

With proper care, many FeLV-positive cats can live happy, meaningful lives, especially when they are monitored closely by a veterinarian.
