What is FeLV?
FeLV is a retrovirus that weakens your cat’s immune system, making them more susceptible to infections. It spreads primarily through close contact such as:
- Saliva when cats groom each other
- Sharing food bowls and litter boxes
- From bite wounds
- Infected mothers can also pass it to their kittens through their milk
Prevention
- Schedule regular testing, especially if your cat goes outdoors or lives with other cats
- Vaccinations (reduces but doesn’t eliminate risk)
- Keep infected cats separate from healthy cats
Symptoms to Watch For
- Fever that won’t go away
- Gradual weight loss
- Dull, unkempt coat
- Red, inflamed gums or mouth sores
- Recurring infections
Trust your instincts—if something feels off, call your vet immediately. Early intervention can make a real difference.
Getting a Diagnosis
Your vet will start with a simple blood test (ELISA) to check for the virus. If it’s positive, they’ll likely recommend a follow-up test (PCR) to confirm whether the infection is temporary or long-term. This helps you and your vet plan the best path forward.
Treatment Approach
FeLV has no cure, but treatment manages symptoms and improves quality of life.
- Regular vet visits to catch problems early
- Nutritional support and hydration to keep them strong
- Preventive vaccinations to protect against other illnesses
- Antiviral medications when appropriate
- Complementary therapies like acupuncture or herbs (alongside traditional care)
For Zakk, I learned how to make his cat food following a species appropriate diet and I bought him a cat water fountain. I believe these two steps helped improve his health and led to a negative FeLV test a year later.
Lifestyle Changes
Diet: High-quality food rich in protein and nutrients supports their immune system. Consult your vet before dietary changes.
Mental Stimulation: Keep their mind active with toys, gentle play sessions, and safe outdoor time (like a supervised backyard adventure). Joy and mental stimulation matter just as much as medicine.
Every cat is unique, and what works for one may not work for another. Pay attention to what your cat needs, celebrate the good days, and be gentle with yourself on the harder ones.
Your love and commitment are already giving your cat something precious: a life filled with comfort, dignity, and care. That’s what truly matters.
