If your cat gets a feline leukemia diagnosis, you may worry about how long it will live. Most felv-infected cats live about 2.4 years. Kittens often live less time, sometimes only a few weeks.

Cat Group	Median Survival Time	Notes
felv-infected cats	2.4 years	Shorter than uninfected cats
Kittens (perinatal)	Weeks	Fading kitten syndrome risk

Early detection with a feline Leukemia test like SaberVet lets you help sooner. Things like infection type, age, and care quality are important.

Many felv positive cats can still have a good life with the right support, food, and regular Veterinary diagnostic checkups.

Feline Leukemia Survival Time

Life Expectancy for Adult Cats

If your cat has feline leukemia, you might worry about its future. Most adult cats with felv infection live between 2 and 6 years after finding out. The median survival times is about 2.5 years. This number comes from studies at Richmond Animal League and Cornell University. Some adult cats with regressive feline leukemia virus can live much longer. They may even live as long as healthy cats. But cats with progressive infection often get very sick. They can get lymphoma, anemia, or leukemia. These problems can make their lives shorter. Healthy cats usually live much longer than felv-infected cats. Many infected cats do not reach old age. Progressive infection means the virus stays active in the body. This causes worse sickness and a higher chance of dying young. felv can cause many problems. But with good care, some cats with felv can still have happy years.

Tip: If you use a feline Leukemia test like SaberVet, you can help your cat sooner. This test gives results in 10 minutes. It helps you and your vet plan the best care. You can learn more about Veterinary diagnostic tools at SaberVet and Cornell Feline Health Center.

Life Expectancy for Kittens

Kittens with felv infection have a harder time. Research from Valley Animal Hospital says kittens with feline leukemia live six months to two years. Kittens often get the worst form of the disease. The virus spreads fast, and their immune system cannot stop it. Because of this, kittens usually do not live as long as adult cats. Here is a table that shows how kittens and adult cats with felv are different:

Aspect	Kittens with FeLV	Adult Cats with FeLV
Susceptibility to Progressive Infection	Higher; rapid progression, poor prognosis	Lower; more likely to have milder forms
Prognosis of Progressive Infection	Poorer; reduced life expectancy	Variable; many live for years with care
Survival Data	High mortality within 3.5 to 5 years, most affected	Many live several years; some reach normal lifespan

Some kittens with felv can live longer if they get good care and stay indoors. Austin Pets Alive! found that 90% of felv positive cats, including kittens, live at least one year after adoption. This shows that with help, even young felv-infected cats can have good lives. For more about Animal diagnostics and Pet diagnostics, visit AAFP Feline Guidelines or PetMD’s feline leukemia page.

FeLV Prognosis Factors

How well cats with felv do depends on a few things. The most important is the type of felv infection. There are two main types: regressive and progressive.

• Regressive infection: The immune system controls the virus. The virus goes quiet, and your cat cannot spread it. Most cats with this type live normal lives. They rarely get sick from feline leukemia.
• Progressive infection: The virus stays active in the body. Your cat can spread it and is more likely to get very sick. The median survival times for these cats is about 2.4 years. Many get lymphoma or anemia.

Infection Form	Immune Response & Virus Activity	Infectiousness to Other Cats	Impact on Life Expectancy and Disease
Regressive	Virus contained; becomes latent.	Not infectious.	Normal life expectancy; low risk of disease.
Progressive	Persistent viremia; virus active.	Infectious for life.	Reduced life expectancy; median survival ~2.4 years.

Other things that matter are your cat’s age, health, and how soon you find the infection. If you use a cat Leukemia test like SaberVet’s, you can find out early. This helps your vet choose the best care. Some cats test positive at first, then later test negative. This means their immune system fought off the virus.

Note: Early diagnosis and regular checkups are very important. They help you manage felv and make your cat’s life better. Learn more about cat Leukemia and cat Leukemia test options at ASPCA’s feline leukemia page.

Quality of Life with FeLV

Supportive Care

You can help felv-infected cats live longer and happier lives by giving them good care. Make sure their home is safe and calm. Build outdoor spaces with strong fences, roofs, and locks so cats stay safe. Use cat-safe plants like catnip, wheatgrass, and lemongrass to make the area fun. Do not use plants like lilies or azaleas because they are dangerous. Play with your cat using feather toys, puzzle feeders, and climbing towers. This keeps them busy and healthy. Here are some ways to help your cat feel better and live longer:

1. Make a clean, safe space and check it often to stop germs from growing.
2. Keep felv-infected cats away from felv-negative cats to stop the spread.
3. Wash your hands after touching infected cats or their things.
4. Feed a good diet with more protein, fat, and energy to help their immune system.
5. Do not give dry kibble to cats with ongoing infection because it is less healthy and can have more germs.
6. If you feed raw food, use food that is treated or cook the meat a little to kill germs.
7. Keep felv-infected cats inside and lower stress by keeping them apart from other cats if needed.
8. Join support groups for advice and help.

Watch your cat’s weight, eating, activity, and mood to spot sickness early. Good food and regular health care can help your cat live longer. SaberVet helps with full FeLV care, including shots and stopping the spread. You can learn more about Veterinary diagnostic tools and Animal diagnostics at SaberVet and Cornell Feline Health Center.

Managing Symptoms

Felv positive cats often have problems like losing weight fast, fevers, diarrhea, pale gums, and trouble breathing. You can help by keeping cats inside, away from other cats, and treating infections quickly. Use antibiotics for infections, give pain medicine, appetite boosters, and fluids to keep them comfortable. Common signs of feline leukemia virus are not wanting to eat, getting sick often, big lymph nodes, bad fur, nerve problems, and being tired. Clean your cat’s eyes, ears, and fur often to stop infections. Shots are important for cats at risk, with kittens starting early and yearly boosters for those who need them.

Balanced, high-protein diet	Supports immune system
Prompt treatment	Prevents complications
Regular cleaning	Reduces risk of secondary infections
Vaccination	Prevents new infections
Frequent monitoring	Early detection of health changes

Regular Vet Visits

Regular vet visits are very important for felv-infected cats. Take your cat to the vet every six months or more if it gets sick. Blood tests can find problems like anemia early. Finding signs like fever, weight loss, anemia, and infections early is key. Your vet may give medicine like steroids, antivirals, chemo, or blood transfusions to help. Medicine and changes at home work together to keep your cat healthy. Watching your cat closely means you can treat small problems fast. This helps your cat feel better and may help it live longer.
