Can a Cat with Feline Leukemia Live with Other Cats


How Contagious is Feline Leukemia?

The VCA Hospitals group does not consider feline leukemia a highly contagious disease. The virus cannot survive outside a cat’s body for long. Close contact with other cats is the primary method of spreading the virus.

Cats’ saliva and blood are primarily responsible for spreading feline leukemia. Infected female cats’ milk, nasal secretions, and feces also spread. While cats can get it, it’s an exclusive virus to cats. The virus can’t be spread to other animals or humans.

Fights or grooming with other cats is the most common way cats’ contract feline leukemia. Cat bites are the most common method of transmission of the virus. Among indoor cats that are the only cats in the home, feline leukemia is less likely to occur because cats contract the virus through close contact with other cats. In addition, cats who spend extended time at boarding facilities or with many feline friends are at a greater risk of contracting the virus.

Can Feline Leukemia Be Transmitted Through

There are a lot of ways feline leukemia can spread. Cats get feline leukemia from the feline leukemia virus (FeLV), which causes the infection. There are numerous ways in which a cat can transmit the virus to another, including:

Close contact with an infected cat: The most common way to spread feline leukemia is by handling an infected cat, grooming them together, sharing food and water bowls, or even sharing litter boxes.

Bite wounds: Cats can spread viruses through bite wounds when they fight.

Mother-to-kitten transmission: The feline leukemia virus can be transmitted to kittens by their mothers during pregnancy, birth, or nursing.

Sharing of contaminated objects: Cats can contract the virus from objects they come into contact with, including food bowls, litter boxes, and bedding.

Fleas: Occasionally, fleas from an infected cat can transmit FeLV to a FeLV-null cat. The virus is more likely to be spread through other means than through cats, but it does happen occasionally.

Neither humans nor other non-feline animals can contract feline leukemia. Vaccination is available for cats that spend most of their time outdoors or live with other cats to prevent feline leukemia infection. You must seek veterinary care immediately if you suspect your cat suffers from feline leukemia.

What Are the First Signs of Feline Leukemia?

Feline leukemia is a severe infection that affects cats. It can cause a range of symptoms and can lead to serious health problems if left untreated. Below first signs of feline leukemia include:

Loss of Appetite: Cats with feline leukemia may lose their appetite and cannot eat as much as they used to.

Weight Loss: Cats with feline leukemia may lose weight rapidly, even if they usually eat.

Lethargy: Cats with feline leukemia may become lethargic and not want to play or be active.

Fever: There is a possibility that cats with feline leukemia will become lethargic and lose their appetite as a result of a fever.

Respiratory Problems: There are respiratory problems with feline leukemia, such as coughing and sneezing.

Vomiting and Diarrhea: Vomiting and diarrhea can cause dehydration in cats with feline leukemia.

Swollen Lymph Nodes: There may be lumps under the skin on cats with feline leukemia, which are caused by swollen lymph nodes.

When you observe any of these symptoms in your cat, you should take them to the vet for a complete examination.

Tests for Feline Leukemia

Taking your cat to the veterinarian if he seems unwell is essential. If feline leukemia is possible in your cat, the veterinarian will perform one or more tests to rule it out.

ELISA Test: Enzyme-linked immunosorbent assays (ELISAs) are most commonly used to diagnose feline leukemia. In the early and late stage of the disease, it detects FeLV particles in the bloodstream. Veterinary offices are usually able to provide results immediately for these tests.

IFA Test: Blood tests such as indirect immunofluorescent antibody assays (IFA) are also standard. Using this method, you can see if your cat has an infection in his white blood cells. Positive IFA results usually mean your cat has FeLV for life, and it’s usually a more advanced stage of the virus.

Stages of Feline Leukemia Infection

Each cat is likely to get the virus in a slightly different way at different stages.

Abortive Infections: Sometimes cats’ immune systems can defend them against FeLV, though these infections are rare. Viruses disappear on their own.

Regressive Infections: The regressive infection affects ten out of every hundred infected cats. Cats with robust immune systems can eliminate viruses from their bloodstream, but those viruses can still be found elsewhere in the body. When this happens, the virus enters the bone marrow. When a cat is contagious again in the future, the virus can resurface, but it can’t infect other cats in this state.

Progressive Infections: FeLV is found in the bloodstream of cats with progressive FeLV infection. There is no resistance to the virus in the cat’s immune system, so he is always contagious to other cats and demonstrates clinical symptoms of the disease.

How to Prevent FeLV

Protecting your cat from infected cats is the best way to prevent feline leukemia. Ensure your cats do not interact with other cats by keeping them inside or outside on a leash. Keeping young, sick, and immunosuppressed cats away from cats with unknown health histories is vital to prevent FeLV transmission. A common question among cat owners is whether a feline leukemia patient can live with other cats.

Welcoming a new cat to a home containing a FeLV-positive cat can cause tension, weakening the cat’s immune system. To stop the illness from spreading, it’s likewise best to keep both good and bad cats apart.

If you have more than cats, you should test all of them and separate them according to their results. FeLV-positive and FeLV-negative cats should have their own food and water dishes and litter boxes and should not interact with each other. Before interacting with other cats or sharing bowls, you should test your new cat for FeLV. If you have multiple cats and don’t know if they have feline leukemia, separate bowls and litter boxes are a good idea.

Do Cats Need the FeLV Vaccine?

It is possible to prevent feline leukemia with a vaccine. To ensure that cats are protected against FeLV, test them for the disease before receiving vaccines. Vaccinating cats after they have been infected will have no beneficial effect. Vaccination against FeLV is not considered a core vaccination for cats since vaccination is often based on the cat’s risk of being exposed to FeLV.

The AAFP suggests that all kittens younger than two years old receive vaccinations by receiving two shots between three and four weeks apart. It is possible to administer the first vaccine at eight weeks. The AAFP recommends boosting the cats’ vaccinations one year after the initial series and determining if further vaccinations are necessary based on their lifestyles.

Indoor cats don’t need FeLV vaccinations, but outdoor cats typically need them every other year or every year. It is recommended that you discuss a feline leukemia vaccine with your veterinarian. However, the FeLV vaccine does not offer 100% protection against feline leukemia, and the best way to ensure your cat’s health is to prevent exposure to infected cats.

The AAFP warns that it requires two to three weeks for a cat to build immunity protection after vaccination, so new vaccination cats should remain inside and away from other cats for at least that amount of time.

How to Take Care of a Cat with Feline Leukemia

Despite various blood treatments being tried, feline leukemia is still incurable. This implies that cats infected with the progressive version of this virus will have to deal with it for the rest of their lives. Despite this, your cat will not have a horrible life from now on.

Keeping cats with feline leukemia healthy is the most important thing. It means keeping up with their vaccinations and veterinary checkups and maintaining a low-stress lifestyle. Secondary infections are more likely to occur in cats with this virus.

When a secondary problem is present, it can have fatal consequences. Keeping a FeLV-positive cat healthy is essential for its long-term health. Depending on the severity, your vet may prescribe antibiotics or give you a blood transfusion to treat secondary infections.


Can feline leukemia be transmitted to other cats?

The virus can spread from one cat to another when they bite each other, clean each other, or (rarely) when they use the same litter box or food dish. A sick mother cat can also give the disease to her kittens before birth or when they are nursing.

Can a vaccinated cat live with a cat with leukemia?

FeLV-positive cats shouldn’t be introduced to an already-infected household since they’re still at risk for getting the infection – even with vaccination.

Can a feline leukemia-positive cat live with other cats?

Taking special precautions when dealing with cats infected with feline leukemia is necessary. If the cat has the disease, it must live with one or two other felines with the same disease or as an only cat.

Why can’t cats with feline leukemia live with other cats?

FeLV can spread to other cats through close contact. Mutual grooming, fighting, and (rarely) sharing dishes are the main ways to spread the infection. FeLV can be spread during birth or nursing by an infected mom.

Can you save a cat with feline leukemia?

The Feline Leukemia Virus, or FeLV, is an infection that hurts a cat’s immune system. It is not a type of cancer, but it does damage the body’s immune system because it is a retrovirus. FeLV-positive cats can live typical, happy, healthy lives but may not live as long as FeLV-negative cats.

Should Cats with Feline Leukemia Be Put Down?

Leukemia in cats does not require euthanasia. In about 70% of cases of feline leukemia, cats can overcome the virus and secondary infections with the proper care. Hey may even be able to heal themselves when they suffer an abortive infection.

Final Thoughts

FeLV is a high virus that affects a cat’s immune system, making them more susceptible to other infections and diseases. Cats with FeLV can spread the virus to other cats through saliva, urine, and other bodily fluids. Therefore, it is essential to keep infected cats separated from other cats to prevent the spread of the virus.

While some cats with FeLV can live for many years with proper care and management, their weakened immune systems make them more susceptible to other illnesses, which can be life-threatening. If you have a cat with FeLV, keeping them as the only cat in the household or with other FeLV-positive cats is best.

You should also take precautions to prevent the spread of the virus, such as washing your hands after handling an infected cat and keeping their litter box and food and water bowls separate from those of other cats.
