Because feline leukemia, or FeLV, causes a slow deterioration, possibly not noticeable until months or years after the initial infection, you may not catch it before the virus moves into secondary viremia. This is the second and more damaging stage of the virus. Have your cat tested if you notice slow, consistent weight loss, pale or inflamed gums, deterioration of fur, chronic diarrhea, seizures, enlarged lymph nodes, anorexia, fever, eye problems, and reproductive problems?
Symptoms of the First Stage: Primary Viremia
Feline leukemia is tricky to spot because there are rarely symptoms associated with the first stage, primary viremia. This is because the virus is attacking the immune system itself. When the immune system is weak, the cat becomes susceptible to everything that attacks. Any kind of secondary infection can become perilous. Often the secondary infection is identified, but the root problem, leukemia, is overlooked. It is extremely important to test for feline leukemia at any sign of sickness, regardless of previous test results.
Symptoms of the Second Stage: Secondary Viremia
The symptoms associated with secondary viremia, or the second stage of feline leukemia in which the bone marrow is infected with the virus, are chronic secondary bacterial, fungus, or viral infections, enlarged lymph nodes and lymphoma, chronic inflammation of tissue, primarily in the mouth, and persistent diarrhea. Look for chronic skin infections, urinary tract infections, and/or upper respiratory infections. It is common that infected pregnant cats cannot bring a pregnancy to full term, often losing the babies early. Any reproductive failure can be an indicator of feline leukemia. Cats with feline leukemia may have a number of problems with their eyes, such as an extended third eyelid and yellowing of the whites of the eyes.
Unfortunately, cancer may actually be a symptom of feline leukemia. While its name belies cancer, to begin with, feline leukemia is not cancer, but it can result in lymphoma or any other kind of cancer or tumor. Because feline leukemia suppresses the immune system to such a great degree, there’s no way to fight the cancer cells, which may otherwise be easily defeated. All of these symptoms are reasons to get your cat or cats tested for FeLV, possibly even more than once.
Frequently Asked Questions
How do cats act when they have leukemia?
Cats with leukemia may exhibit symptoms such as loss of appetite, weight loss, lethargy, swollen lymph nodes, anemia, infections, easy bruising, or bleeding. These symptoms can vary greatly in severity and may not all be present in every cat with leukemia. If you suspect your cat has leukemia, it is important to have them evaluated by a veterinarian.
How long can cats live with feline leukemia?
The lifespan of a cat with feline leukemia can vary greatly depending on the severity of the disease and how it is managed. On average, cats with feline leukemia may live anywhere from a few months to a few years with proper treatment and care. However, some cats can survive for much longer, while others may have a more rapid progression of the disease, which is why t is important to work closely with a veterinarian to determine the best course of treatment and care for your cat.
Is feline leukemia always fatal?
Feline leukemia can be a fatal disease, but it is not always fatal. The severity of the disease and the response to treatment can vary greatly from cat to cat. With proper veterinary care, some cats with feline leukemia can live for several years or more. However, the disease can also progress quickly and be fatal in a matter of months.
How long does feline leukemia take to show symptoms?
The time it takes for symptoms of feline leukemia to appear can vary greatly, but it usually takes several weeks to several months after the initial infection. Some cats may not show symptoms for several months or even years after being infected. It is important to have your cat tested for feline leukemia if you suspect they may have been exposed to the virus, even if they do not have any noticeable symptoms. Early diagnosis and treatment can greatly improve the prognosis for cats with feline leukemia.
Can cats fight off feline leukemia?
Some cats can fight off feline leukemia and become carriers of the virus without showing symptoms, while others may develop the disease. The ability of a cat to fight off the virus can depend on several factors, including its overall health, age, and immune system function. However, it is also possible for a cat to become infected with the virus and rapidly develop the disease, even if they are otherwise healthy.
