Treating Your Cat For Felv

What is Feline Leukemia Virus?

There is no medication that can wipe out FeLV, but supportive treatment is available to help with symptoms. Steroids, antiviral drugs, chemotherapy, and blood transfusions may be utilized to manage feline leukemia.

Steroids are used to treat cancerous lymphocytes in the blood, but they can also leave a cat open to developing other diseases, because steroids further weaken the immune system. An antiviral can reduce the amount of virus present in the blood and is easier on the body than chemotherapy. However, antivirals are very expensive, and it is currently unclear how helpful they may be. Antibiotics are given when any bacterial infections arise. Blood transfusions may also be necessary in the case of severe anemia.

Is There A Cure

Unfortunately, there is no cure for this condition, and the cats life will typically be shortened due to it. However, how much the disease will impact the cat is hard to predict. Some will live with the condition for years. Once a cat becomes infected, it must be kept separate from other cats. It can not be allowed to wander freely outside and should stay inside the house.

While there is no cure, there are multiple ways that you can prolong a cats chances when they have been diagnosed with this disease. These cats should be:

  • Kept indoors and away from other cats

  • Kept on a strict diet without raw meat or eggs

  • Have regular checkups with their vet

  • Seek veterinary care at first sign of an illness

  • Kept up-to-date on vaccines

  • Have regular fecal tests and deworming

Remember, cats with FeLV are more prone to developing other illnesses so you must do what you can to protect the state of their health.

How Is Felv Managed

Although there is no known cure for FeLV, supportive care can improve the quality of life, health, and longevity of cats with FeLV. An infected cat may live free of FeLV-related disease for her entire lifetime. Any secondary infections and diseases can be treated as they occur.

Some recommendations for supportive care include:

  • Minimizing stress. Consider products like FELIWAY┬«, which mimics a cats natural calming pheromones.
  • Feeding em the good stuff. Make sure your cat is getting good nutrition and consult with a veterinarian to determine the healthiest possible food.
  • Being vigilant. Promptly taking cats to the veterinarian when they appear ill is especially important for cats with FeLV. Their weakened immune systems can cause them to contract other diseases or infections more easily. If you watch closely and get them immediate treatment, you can better protect them.
  • Staying up to date. Keep up with the latest information on FeLV in case new treatments or diagnostic developments emerge.
  • Seeking support. Ask for help from fellow caregivers caring for cats with FeLV. You may have someone in your area with lots of experience and helpful advice. Try reaching out to our Feral Friends Network members near you.

Felv Testing And Diagnosis

Because this disease is highly contagious and infection comes with serious health consequences, the AAFP recommends that cats should be tested when they are:

  • Sick, regardless of age, despite previous negative test results or vaccination
  • About to be adopted or brought into a new home, regardless of age
  • At risk of exposure even if their most recent test was negative
  • If their FeLV status is unknown
  • About to be vaccinated against FeLV or FIV

Testing is done using a small blood sample. The first test is typically used as a screening tool and can be performed at your veterinary clinic with results in as little as 20 minutes. A negative result from the first screening test is highly reliable. However, if the result is positive, the next step is to have a confirmatory test done by an outside laboratory, which takes a couple of days.

FeLV can usually be detected in the blood within 30 days of exposure . If your cat tests negative, but they could have been exposed to FeLV less than 30 days ago, your veterinarian will likely want to repeat the test at least 30 days after their last potential exposure.

Can Cats With Felv Live A Normal Life

Feline Hiv Contagious To Other Cats

The information we discussed above may be daunting, but its important to remember one thing FeLV does not have to be a death sentence.

Its unfortunate how many cats in shelter and rescue situations are euthanized due to their positive result, but the diagnosis itself does not mean your cat will have a life filled with suffering.

Yes, they may struggle at some point, but many can live a normal life until then.

If a cat is generally healthy at the time of diagnosis, most will have a standard life expectancy of 2-3 years.

Your cat could also be one of the lucky ones that fight off the virus with their immune system, meaning they could have many years ahead of them before any complications arise.

If your cat is not suffering at the point of their diagnosis, euthanasia does not have to be the only option on the table.

Cats with FeLV can continue to live normal lives as long as you are dedicated to monitoring their weight, their appetite, their energy levels, their litter box habits, and their general appearance in terms of skin and coat health.

Staying on top of any changes can allow you to seek veterinary care at the start of any health complications, giving them the chance at proper management.

Your cats life may be shorter than others, but their life can still be wonderful up until you have to say goodbye.

Again, every case will vary, so we always suggest speaking with your vet about your cats prognosis.

Treatment For Feline Leukemia Virus

Eighty-five percent of cats persistently infected with feline leukemia virus die within three years of diagnosis. However, regular veterinary check-ups and good preventive health care can help keep these cats feeling well for some time and help protect them from secondary infection. Twice-yearly physical examinations, laboratory testing, and parasite control can prevent complications and identify problems quickly. All FeLV infected cats should be kept indoors and be neutered.

There is presently no cure for FeLV infection. Secondary infections can be treated as they appear, and cats with cancer can receive chemotherapy. However, the prognosis is grave for cats with bone marrow compromise or widespread lymphoma.

What Complications Can Feline Leukemia Cause

As we mentioned before, FeLV carries a devastating stigma. While many believe that FeLV will automatically decrease a cats quality of life, this is not always the case.

Up to 30% of cats will effectively eliminate the virus with their immune response , and will go on to live a normal life.

Cats will still be able to infect other cats when the virus is present within their body, but they may be able to eliminate the virus before they ever develop serious health complications as a result.

However, this is the best case scenario, and is considered the most rare of all possibilities.

If 30% of cats will effectively eliminate the virus, then 70% of cats will fall victim to a permanent infection of FeLV.

These cases are known as either progressive or regressive infections, varying in severity based on the bodys immune response to the virus.

These are the cats that will easiest spread the virus to other cats in their life, as well as experience FeLV related complications down the line.

It can take years for cats to develop secondary complications from the virus, which is why so many cat owners are unaware that their pet is infected.

This is also when most infection occurs within multi cat homes, as the owners were simply unaware of what preventative measures should have been taken.

The leukemia is serious in itself, but it is often the secondary disease down the line that makes this virus so devastating.

Detection Of Intracellular Gag Protein Using The Immunofluorescence Assay

The first method that allowed FeLV detection in progressively infected cats under field conditions was the indirect IFA, introduced in 1973 . It was based on the observation that granulocytes, lymphocytes, and platelets in progressively infected cats contain gag components, which may be detected by IFA in blood smears. Thus, it becomes positive later than the ELISA and only in the phase of the second viraemia, when bone marrow cells are infected. The diagnostic sensitivity of IFA is significantly less than that of the ELISA . If a progressively infected cat has leukopenia or if only a small percentage of peripheral leukocytes are infected, the presence of FeLV infection may be overlooked using IFA tests. Furthermore, all eosinophils have a tendency to bind the FITC conjugates used for IFA resulting in false positive tests if slides are not read carefully .

Is There A Vaccine For Felv

Understanding Feline Leukemia Virus and FIV in Cats

There is a vaccine for FeLV. Kittens are usually vaccinated at around 812 weeks of age, then given booster vaccinations three or four weeks later. Yearly boosters are given as long as cats are at risk for exposure. These include cats that live with other cats or are allowed to go outdoors. If a cat is considered to be at low risk for FeLV, your vet may recommend not vaccinating. Its best to talk with your doctor and weigh the options.

Vaccinations and limiting exposure are the best ways to prevent your cat from contracting FeLV. Once infected, cats cannot be cured of FeLV, but with proper management and care they can enjoy a normal life for a few years after the initial diagnosis.

Epidemiology And Transmission Of Feline Leukemia Virus Disease

The prevalence of FeLV infection has been documented in several studies in North America and worldwide. In a large 2010 study in the US and Canada, the prevalence of FeLV was determined to be 3.1%.1 References Feline leukemia virus is one of the most common infectious causes of disease of cats globally. Infection with FeLV can cause a variety of clinical signs, impacting a cat’s longevity and… read more There was an increased risk to cats with an outdoor lifestyle, sexually intact males, and cats with other disease conditions . In the US, prevalence was highest in the Midwest and West and lowest in the Northeast. In 2019, a large European prospective study of FeLV viremia in cats visiting a veterinary hospital found an overall prevalence of 2.3%. The highest prevalence was in southern Europe and the lowest prevalence was in northern Europe . Risk factors in the 2019 study included sexually intact males, access to the outdoors, ages 1 to 6 years, living in a group of 5 or more cats, and illness. Although vaccination and test and removal prevention methods have led to decreases in the prevalence of FeLV since the mid-1980s, stagnation in this decline has been reported in some countries in the late 2010s.2,3,4 References Feline leukemia virus is one of the most common infectious causes of disease of cats globally.

How Can My Cat Get Feline Leukemia

FeLV is transmitted from other infected cats “shedding” the virus a time when the virus is replicating in the body and released into the environment through their saliva, nasal secretions, urine, feces, and milk. This means cat-to-cat transfer may occur during grooming, through bite wounds, and even by simply sharing feeding dishes and litter boxes. It can also be transmitted from infected mother cats to their kittens while still in the womb or nursing.

New Cat Owner What To Know About Feline Leukemia

What do new pet owners need to know about feline leukemia ? According to the Merck Veterinary Manual, this common cat disease affects three percent of U.S. felines. If you recently adopted a cat, take a look at these top FeLV questions.

Is Feline Leukemia a Type of Cat Cancer?

Leukemia in humans is a form of cancer. But for cats, this is a different type of disease. The V in FeLV comes from the word virus. Unlike human leukemia, feline leukemia is from a communicable virus. This means FeLV is an illness that a cat can catch from another cat, provided the other feline is infected with the virus.

Even though feline leukemia starts as a virus, it can cause a form of cancer in cats. It can also result in anemia or depressed immune function.

How Can a Cat Catch Feline Leukemia?

Is FeLV a contagious disease that spreads through cat sneezes, coughs, or something else? The feline leukemia virus doesnt spread via passing contact with an infected cat.

Instead, this virus spreads through body fluids and feces. A cat infected with FeLV can pass the virus to another feline through their urine or saliva. This can happen during grooming, fighting, or sharing a litter box or food and water bowl. An infected mother can also spread the FeLV virus to her kittens while pregnant or nursing.

Cats can get Leukemia and it

There are several tests that can determine whether a cat is infected with FeLV. One test called ELISA looks for the virus in the blood. This test will determine whether the cat has the virus but not at what stage. Its possible to test positive on this test and find that the virus hasnt infected the bone marrow. This means that the cat could still fight the virus off themselves.

Be aware though that false positives and negatives are common. As such, if positive, a second test will usually be completed about twelve weeks after the first.

Classification Of Viral Genome

Feline leukemia virus is a retrovirus in the family Oncovirinae. As a retrovirus, FeLV is an enveloped virus with a positive-sense single-stranded RNA genome, which relies on a double-stranded DNA intermediate in its life cycle for replication ssRNA-RT). Other oncoviruses include feline sarcoma virus , mouse leukemia viruses, and two human T-lymphotropic viruses.

Clinical Signs Of Feline Leukemia

This disease affects cats in a variety of different ways. Because of the presence of infection, it is the leading cause of leukemia in cats and can develop into blood disorders and a decrease in immunity. Cats with FeLV are prone to other diseases and poor quality of health because of decreased ability to fight off infection brought on by viruses, bacteria, fungi, and so on.

Signs associated with this infection in cats include:

  • Loss of appetite/weight loss

What Are The First Signs Of Feline Leukemia

Cats who become infected with feline leukemia may show no symptoms at first. They could seem perfectly healthy for weeks or months, but gradually deteriorate in health. Some cats will go through phases of illness and health in a repetitive cycle.

  • Pale gums
  • Yellowing of the mouth and eyes
  • Diarrhea
  • A lackluster coat of fur
  • Bladder, lymph, skin, and upper respiratory infections
  • Anemia
  • Loss of appetite
  • Reproductive failure

When an aggressive form of feline leukemia is present, other conditions can arise because of it. These conditions include lymphoma, a compromised immune system, and in previously fertile cats, infertility and abortion.

How Do Cats Become Infected With Feline Leukemia

How to care for a cat with feline leukemia

Feline leukemia is generally transmitted through contact with saliva from an infected cat. Certain social behaviors such as mutual grooming and sharing food or water bowls can spread the disease. Kittens can become infected during fetal development or during the first days of life as their mothers nurse and care for them.

FeLV is killed by many disinfectants and does not live for very long in the environment, so contact with an infected cat is necessary for disease spread. However, predicting which cats can transmit the disease is complicated because some cats that are contagious dont develop signs of infection.

Feline leukemia is not cancer. Feline leukemia virus in cats is a common disease with a terrible stigma. Leukemia in cats is extremely contagious.

Is Feline Leukemia Airborne

Transmission is possible via the saliva of sick cats, either directly or indirectly through contaminated items such as food and water bowls. FeLV may also be detected in other secretions, including urine and feces, but this is less frequent. The distribution by air is not an issue. FeLV is not extremely resistant to environmental conditions.

Felv Tests Can Provide False Positives Or Inconclusive Results:

  • A cat in the initial stage of FeLV infection may test negative for FeLV even if they are infected. A cat exposed to FeLV may test positive during the transient phase of the infection and then test negative if the virus is overcome. Overall, results can be shaky and difficult to trust.
  • In general, FeLV tests are not 100 percent accurate and can yield false positive results.

How Felv Is Diagnosed

What Is Feline Leukemia (FeLV)?

The truth is that making a clinical diagnosis is not very reliable. The symptomatology may coincide with that of many other diseases. In addition, some infected cats remain asymptomatic during the year. In these cases, the most reliable is to perform diagnostic tests. Different tests are available to see if a feline is infected. It is very important to perform a test as soon as possible since there is a suspicion that the disease may exist and above all if there are other cats near the patient.

If any test is positive, it is appropriate to test all felines that have been in contact with the one presenting the disease. By the way it is also important to perform the test on cats of unknown origin those found on the street or adopted in a protective.

The enzyme linked immunosorbent ELISA test is the test most used by veterinarians. It is done through a blood sample, since other fluids are not as reliable. This test should be repeated several weeks later. Sometimes it is necessary to practice supplementary tests.
