What Are The Symptoms Of Feline Leukemia – This is part 3 of this 3-part series on FeLV. Part 1 covers transmission and Part 2 covers symptoms and diagnosis.
At the time of writing, there is no cure for FeLV; some therapies can reduce the amount of FeLV in a cat’s bloodstream, but have significant side effects and are not effective in all cases.

What Are The Symptoms Of Feline Leukemia
Veterinarians typically treat and treat FeLV-positive cats exhibiting disease symptoms with antibiotics for bacterial infections or blood transfusions for severe anemia.
Cat Leukemia: Causes, Signs, & Treatment
Although a FeLV vaccine is available, it is not considered a core vaccine and does not protect 100% of cats. The American Association of Feline Practitioners’ 2020 guidelines recommend FeLV vaccination for all kittens up to 1 year of age, especially in high-infection areas, because they are more susceptible to progressive infection, FeLV-associated disease, and death if exposed for FeLV compared to adult cats.
Booster vaccination of uninfected cats is only recommended for cats considered to be at risk of exposure to FeLV-infected cats, for example in a household with FeLV-infected cats, because isolation and hygiene protocols may not be consistent. Vaccination of FeLV-infected cats has no therapeutic value.
Infected females can transmit FeLV to their kittens in utero or via infected milk. Infected females should not be used for breeding and should also be spayed to eliminate the stress of heat cycles if their condition is stable enough for surgery.
Routine veterinary surveillance every 6 months of FeLV-positive cats should assess weight, appetite, activity level, elimination habits, mouth and eye appearance, and behavior; a complete blood count should also be performed at least every 6 months due to the greater frequency of virus-related hematological disorders. Annual serum analysis and urinalysis should be performed annually; urine samples should be collected by cystocentesis. Parasite prevention should be considered to reduce the risk of secondary infection and disease. Infected cats can be kept in the general hospital wards, but should not have direct contact with other hospitalized cats.
Symptoms Of Feline Leukemia
The American Association of Feline Practitioners recommends that FeLV-infected cats, especially those showing signs of immunosuppression, receive a single killed FDCVR (Feline Distemper/Panleukopenia, Calicivirus and Viral Rhinotracheitis) vaccine 1 year after the last dose of the initial series , then no more frequently than every 3 years.
A nutritionally balanced, complete cat food suitable for the cat’s life stage is especially important for infected cats. Raw meat and raw dairy products are not recommended because the risk of foodborne bacterial and parasitic diseases is likely to be greater for FeLV-infected cats due to their suppressed immune systems.
The survival time of FeLV-diagnosed cats is 2-1/2 years, they can live normal lives for longer periods when properly cared for by their pet parents and veterinarians.
Cat Problems And Health Issues, Causes, Symptoms, And Treatments , Feline Leukemia Virus Felv
Despite its name, FeLV is not actually a form of cancer or leukemia. Instead, it is a retrovirus (in the same family as Feline Immunodeficiency Virus or FIV) that is found in approximately 2-3% of all cats in the United States. FeLV invades and replicates in cells of the cat’s immune system and tissues that form blood cells. Low white blood cell count is a sign of a weakened immune system, and diseases acquired from this virus are typically related to a weakened immune system.
While FIV was previously thought of as the “fighting disease”, FeLV has been known as the “love virus” or “friendly disease” due to its ability to be easily transmitted to other cats through mutual grooming. It can also be passed through shared food and water bowls or litter boxes, fights or from a pregnant or lactating cat to her kittens. The virus emits large amounts of saliva and nasal secretions and can also be found in the urine, faeces and milk of infected cats.
Feline Leukemia Virus (felv): What You Need To Know
Feline leukemia is only passed from cat to cat, meaning that humans, dogs and other animals cannot get it.
A blood test can confirm if FeLV is present in your cat. If the first test is positive, a second sample is sent to a laboratory to confirm the diagnosis. Cats can test positive within a few weeks of exposure, and most cats that test positive were infected within 30 days. Younger cats are more susceptible and, unfortunately, infected kittens have an average lifespan of only two years. Most vets recommend testing again after six weeks if a test has questionable results.
While certain symptoms can be managed and supportive care can be offered, unfortunately there is no cure for feline leukemia. There are some expensive treatments available from some vets, but these are outside the scope of the shelter.
And while there is no commercially available vaccine against FIV, there is a vaccine available against FeLV in negative cats. The Feline Leukemia vaccine is recommended as a core vaccine by the American Animal Hospital Association and the American Association of Feline Practitioners.
Cancer In Cats: Causes, Symptoms, & Treatments
Spaying and neutering your cats and vaccinating your FeLV-negative cats is the best way to stop the spread of FeLV.
Although a diagnosis of FeLV can feel devastating, it is important to realize that cats with FeLV can live mostly normal lives for long periods of time – although their lifespan
Because FeLV affects the immune system, like FIV, it means your cat is more susceptible to other illnesses and may not recover as quickly from common infections or from surgery. It is important to note that FeLV itself does not cause death; rather, it is the subsequent diseases that often arise due to the weakened immune system.
Once a cat has been diagnosed, careful monitoring of weight, appetite, activity level, elimination habits, mouth and eye appearance, and behavior is an important part of managing the disease. Maintaining dental care should be a priority, as infections in the mouth and gums can pass through the bloodstream and cause more problems. Raw foods and unpasteurized dairy products should be avoided because of their high risk of foodborne bacterial and parasitic infections. A high-quality diet and a low-stress environment will also be beneficial.
Kittens Born With Feline Leukemia (felv): Symptoms, Treatment
At the Cat Care Society, when we see a positive FeLV test, we have a few possible courses of action. After another test, we can find out if the disease is present in their bone marrow or blood. If it’s only in their blood, the disease hasn’t developed yet, and the cat actually has a chance to kick the virus out through his or her immune response. If it has already reached their bone marrow, the bad news is that they will have FeLV for the rest of their lives. It can lie dormant for a while and the cat appears to be fine, but FeLV can rear its ugly head years down the road, wreaking havoc on the immune system and gradually worsening a cat’s health. If this confirmatory test is negative, it may mean that the disease is “floating around” and has not reached the marrow yet, and we will test again in a month, explained CCS’s chief veterinarian Dr. Cecily Palamara.
If a FeLV-positive cat is asymptomatic, this is good news for his or her quality of life! However, if the disease is progressive, the cat may show symptoms of anemia, lethargy, malaise and weakness. Because their immune system is suppressed, it can develop into leukemia or lymphoma. These cats often die young and can be annoying to navigate.
Due to the severity of this disease, FeLV cats should be the only cat in a home or mated with another FeLV+ cat and should be kept indoors.
Cat Care Society provides a safe haven for many cats with special needs because we believe that all cats deserve a chance at a loving home, regardless of medical diagnosis. That’s why we take in many FIV and FeLV cats who wouldn’t have a chance at other shelters.
Feline Leukemia: Symptoms And Treatments For Cats
When we receive new adult cats at the shelter, we screen for both FIV and FeLV so we know what we’re up against.
Many shelters will not adopt a cat with FeLV because they do not want to put that burden on adopters, although some cities and states across the US are becoming more progressive in
