Is There A Vaccine Available For Feline Leukemia Virus

Veterinarian at Cambridge Cat Hospital discussing feline diseases – FeLV and FIV

Although there is no cure, there is a fairly effective vaccine available for feline leukemia. It does not have a 100 percent success rate and is not considered a core vaccine, but it can be beneficial. Since it does not work for all cats, preventing exposure will remain important even for vaccinated cats. The vaccination also will not cause false positive test results for the ELISA, IFA, or other feline leukemia blood tests.

Many of the available vaccines are a combination of vaccines that also protect against feline herpesvirus , calicivirus, and panleukopenia . All of the available cat leukemia vaccines have been tested and found safe and effective if they are administered as directed by a veterinarian.

Kittens are generally vaccinated for feline leukemia virus around eight to nine weeks old. They are then given booster vaccinations three or four weeks later, depending on the vaccine. This is followed by boosters every year for as long as they are at risk for exposure. These cats include cats that go outside or live with other cats. If a cat is thought to be at low risk for feline leukemia, a vet may not recommend the vaccination at all.

Felv In Cats: How Serious Is It

“Many people think FeLV cats are sick and dying and have no quality of life,” says cat caregiver Joni Miller. “The reality, though, is felines who are positive for the virus can remain healthy for months or years after their diagnosis until the virus becomes active.” In fact, some cats can live to be 10 to 15 years old if they are diagnosed as an adult. Whatever length their life ends up being, their time can be joy-filled.

So what exactly does the future hold for a cat who is diagnosed with FeLV? There are many factors, the biggest of which is the cats age more specifically whether the cat is a kitten or an adult when they acquire the virus.

The virus is harder on kittens than adults. Sadly, most kittens succumb to the disease before their second birthday. Nevertheless, even though the virus can be harsh on kittens, this does not mean their lives are without worth.

General Cost To Treat Feline Leukemia

Initial testing in cats for FeLV as well as veterinary examination will typically cost $100-$200. Other secondary medical conditions that may occur and are not caused by FeLV vary in treatment from $100 to treat an upper respiratory infection to thousands of dollars to treat stomatitis.

Since there is no treatment for end-stage FeLV, there is no true cost other than possibly palliative care .

How Often Should Cats Be Vaccinated For Feline Leukemia

Duration of immunity depends on the precise vaccine used and the immune response of your cat: this can vary from 12 months to two or three years. Revaccination also depends on other factors such as the risk of your cat to exposure to the virus. The topic should be discussed with your own veterinarian at your cats annual veterinary check as part of their routine health care.

What Are The First Signs Of Feline Leukemia

Living with 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.

Protect Your Pet From Communicable Illnesses

The first vital step any pet owner can make in fortifying a cat’s immune system is to keep the cat indoors. This advice extends to otherwise healthy cats that are not infected with feline leukemia. Indoor cats live significantly longer than outdoor felines. This is partly due to the fact indoor cats are not exposed to the cocktail of harmful and communicable cat illnesses that lie waiting in the outdoor environment. Maintaining an outdoor animal may initially seem like a good idea because many people believe cats need to roam as they do naturally in the wild. However, wild cats frequently suffer from illnesses and often lose their lives to predators. So, keeping your cat indoors is probably the better of the two options.

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.

Is There A Vaccine To Protect Against Felv

Yes, there is a vaccine against FeLV available for use in cats and kittens. The vaccine is not beneficial if your cat is already infected with FeLV. The vaccine can protect against the development of a progressive FeLV infection when it is given to an FeLV-negative cat and administered correctly as an initial series with annual boosters. This vaccine is only recommended in certain cats the recommendation to vaccinate for FeLV is based on individual risk factors and an assessment by a veterinarian, including a negative FeLV test prior to vaccinating. No vaccine is 100% effective at preventing infection and disease.

Best Practices For Veterinarians And Animal Shelters

What is Feline Leukemia Virus?

A cat who tests positive for FeLV at a veterinary clinic or shelter should not be euthanized unless she is already ill or suffering beyond what can be treated. FeLV testing should be done with a plan to help the cat if she tests positive, not to end her life.

No veterinary hospital or shelter should prohibit a cat who tests positive for FeLV from leaving with her owner or caregiver. People should be allowed to take their cat regardless of test result. If a healthy community cat is brought into a veterinary clinic for spay and neuter as part of Trap-Neuter-Return , she should not be tested for FeLV at all.

Alley Cat Allies recommends that adoptable cats in shelters be tested for FeLV in-house only if they will be placed for adoption regardless of the result rather than euthanized. Shelters can also simply advise adopters to have their new cat tested for FeLV at a veterinary clinic and not test in their facilities at all.

All shelters should implement programs that help find homes for adoptable cats who test positive for FeLV. Many shelters already have model programs that can be used as blueprints.

A Cat Leukemia Loophole

Also, theres a loophole that some fortunate kittens are able to slip through. Consider the journey of littermates Socks and Mr. Jimmers, two young cats who are available for adoption from the Sanctuary.

First a little background. There are two tests that are used to determine a cat’s FeLV status: a Snap or ELISA, enzyme-linked immunosorbent assay, and an IFA, indirect immunofluorescent anitbody assay. Joni explains, “The Snap test determines if the virus is present in the cat’s system, but not at what stage. A positive on the Snap could mean the cat was recently exposed and fighting it off, or that the cat is chronically infected.”

When these two boys came to the Sanctuary as kittens, they tested faintly positive for FeLV on the Snap test and positive on the ELISA test.

A positive on the Snap test can mean that the virus hasnt gotten into the bone marrow, so they might be able to fight it off. For this reason, this duo lived at Cat World Headquarters, away from other cats with the virus. In time, they tested negative for FeLV on both tests.

Treatment Of Feline Leukemia Virus

Unfortunately, there is no cure for FeLV. But that doesn’t mean hope is lost. For FeLV-positive cats, long term management should focus on the treatment of secondary diseases. Prompt attention should be given to any medical problems that your FeLV-infected cat develops, and preventive healthcare is paramount. Veterinary checkups should be done every six months.

Is There A Vaccine For Feline Leukemia

Fortunately, there is a vaccine for FeLV. Talk to your veterinarian about your cat’s risk factors and whether they should receive the vaccine. The AAFP recommends FeLV vaccination for:

  • Kittens and young adult cats under one year of age
  • Cats who go outdoors
  • Cats who have direct contact with cats of unknown FeLV status or in high turnover situations, such as foster homes and other group housing
  • Cats who live with FeLV-positive cats

Symptoms Of Leukemia In Cats

How Long Do Cats Live?

According to PetMD, there are many feline leukemia symptoms that you should look for. Some feline leukemia symptoms in cats are:

  • Progressive weight loss

  • Blood transfusions

  • Dietary supplements

  • Various immunomodulatory drugs , like Interferon, Acemannan, and ImmunoRegulin.

A few medications have shown great promise in treating feline leukemia virus, such as antivirals used in human AIDS treatment. Laboratory testing, twice-yearly physical examinations, and parasite control can help prevent complications and identify any problems quickly. All cats with feline leukemia should be kept indoors and neutered if not already.

Feline leukemia virus makes it hard for your cats body to respond to treatment if your cat is ill. Your vet will prescribe medication that will treat the symptoms. Your vet may hospitalize your cat in case of severe secondary infections, like weight loss with muscle loss, or low red-blood-cell count. In these severe cases, your cat will be kept under hospital care until the condition stabilizes.

Paying For Feline Leukemia Virus

Do you know that feline leukemia virus is a very contagious and severe viral disease which affects only cats? Knowing the warning signs and symptoms of cat leukemia are important so that you can take proper steps to care for your furry friend.

Fortunately, there are several ways you can protect your cat from exposure to feline leukemia. Feline leukemia virus is one of the most infectious diseases that affect cats globally.

Cat leukemia manifests mainly through malignancies, profound anemia, and immunosuppression. It infects domestic cats, kittens and other species of Felidae.

Also, feline leukemia is the second leading killer of cats. Feline leukemia kills 85% of persistently infected cats within only three years of diagnosis. It is worth mentioning that the cats and kittens at the highest risk for contracting feline leukemia virus are those that live with infected cats or cats that have an unknown infection status.

Controlling feline leukemia transmission can be difficult as the virus easily passes from one cat to another through various means, such as blood, saliva, and to some extent, feces, and urine. Also, the virus doesnt live long outside the cats bodyusually just a couple of hours.

How Is Felv Spread

FeLV is spread primarily through cats saliva. It can also spread through blood, tears, feces, and urine.

Most cats get the virus from their infected mothers at birth or through prolonged direct contact with FeLV-positive cats, such as mutual grooming. FeLV also spreads through bite wounds, such as those caused by male cats fighting.

In rare instances, FeLV can spread through the shared use of litter boxes or feeding dishes.

Diagnosing Lymphoma In Cats

The only way to accurately diagnose lymphoma in cats is by identifying the cancerous cells under microscopic examination.

Your veterinarian may perform diagnostic blood work and x-rays to get a full picture of what your cat is facing, but will require more to give you an exact answer.

The only way to examine the potentially cancerous cells under microscopic examination is by performing a fine needle aspirate or a surgical biopsy.

An FNA can be used if your veterinarian can easily feel and make contact with the area in question.

For example, if your veterinarian can feel a thickened area in your cats GI tract, they may be able to reach the area with a needle and obtain a small sample.

Your veterinarian can then examine this sample under the microscope themselves, or send the slides to a diagnostic lab for a more extensive search.

This is usually the first diagnostic performed due to it being minimally invasive, as well as much more budget friendly.

If your veterinarian is unable to perform a fine needle aspirate, the next step would be a surgical biopsy.

This will be performed under general anesthesia, and will involve your veterinarian collecting a sample of the tissue in question.

This is usually only possible in cases of potential GI lymphoma, as your vet can remove a small section of the thickened intestine.

This becomes much more challenging in cases of renal or mediastinal lymphoma.

Cat Behaving And Feeling Normal

Understanding Feline Leukemia

Last but not the least, yes, you need to make sure your cat is feeling normal to conclude that it is free from the leukemia virus.

This needs to be said because sometimes, test results can be a bit inaccurate.

Also because if it is not acting normal, you may need to get regular check-ups to the vet to ensure everything else is fine internally.

How Is Cat Leukemia Diagnosed

If your veterinarian suspects your cat has FeLV, they can be screened through a simple ELISA snap blood test. If your veterinarian uses a reference laboratory, snap test results can be available within 24 hours. In some instances, this test can also be performed right in the office while you wait.

The snap test detects the virus in the blood however, it is not 100 percent accurate. If a cat tests positive for FeLV, another blood sample must be sent to the lab to confirm infection through an IFA test . In some cases, a PCR blood test is run as well. Your vet will be the best resource on which test is right for your cat.

Feline Leukemia Prevention In Cats

An FeLV diagnosis can be devastating for cat owners but a vaccine is available for cats who have not previously been exposed to the virus. The American Association of Feline Practitioners recommends that most kittens receive two vaccinations plus a booster at 12 months of age. Your veterinarian will determine if your cat is a good candidate for the FeLV vaccine.

Ensure you bring your newly adopted kitten for a veterinary examination and FeLV testing before introducing them to other feline family members. Several blood tests during your kittens first six months may be required to ensure they are FeLV-negative. Other prevention methods include:

  • Keeping your cat indoors to prevent exposure
  • Scheduling regular veterinary check-ups
  • Avoiding contact with unvaccinated cats
  • Scheduling twice yearly or more frequent veterinary visits for FeLV-positive cats to manage secondary infections or diseases
  • Avoiding bringing new cats into a home with an FeLV-positive cat

Ask your family veterinarian to determine if your cat is a good FeLV vaccination candidate. If your cat shows any FeLV signs after hours bring them toAnimal Emergency Care for immediate care. #AECprevents

How Is Feline Leukemia Virus Treated

Eighty-five percent of cats that are persistently infected with the disease die from it within three years of diagnosis. But with regular check-ups at your veterinarian, including twice-a-year physicals, and routine testing, you can keep your cat feeling well and prevent secondary infection.

While there is not currently a cure for feline leukemia virus, the secondary infections can often be treated as they appear. Cats with bone marrow leukemia or widespread lymphoma will have a grave prognosis. Even with aggressive treatment, some cats can still die from the virus.

There is no medication that can eliminate the virus, but many medications are available to help with symptoms. Steroids, antiviral drugs, chemotherapy and blood transfusions are commonly prescribed to treat feline leukemia. Steroids are used to decrease the number of cancerous lymphocytes in the blood, but they also leave the cat vulnerable to other diseases because they can weaken a cats immune system.

An antiviral can reduce the amount of virus present in the cats blood and are easier on the cats body than chemotherapy. The risks and benefits of the treatments must be weighed, while keeping in mind that they cannot get rid of the virus, but can put a cat into remission. Veterinarians generally will prescribe antibiotics for any bacterial infections or perform a blood transfusion in an instance of severe anemia.

What Is The Life Expectancy Of A Cat With Leukemia

Kitten Rescue â Feline Leukemia Sanctuary Room Cat ...

Estimating how long a cat lives with feline leukemia is a complex issue and difficult to pinpoint even for veterinarians who are experts in this pathology. If we want to mention some figures, we can say that about 25% of cats with feline leukemia die within 1 year after being diagnosed. But 75% survive for 1 to 3 years with the virus active in their bodies.

Many owners feel desperate when they think that their cats can carry the Feline Leukemia Virus , but this diagnosis does not always mean a quick death sentence. In fact, about 30% of FeLV infected cats carry the virus latently, and do not even develop feline leukemia.
