It’s especially hard knowing that there is no known cure for this virus. Even though there is not a cure for feline leukemia it doesn’t mean a cat that is diagnosed is bound to live a short life.

Cats diagnosed with this virus can live for many years after contracting it. 

The first thing to consider is the age of the cat. Unfortunately, If a kitten were to contract feline leukemia it isn’t easy for it to fight the virus.

Many kittens that get this virus don’t make it to their second birthday. Even with a short life expectancy, a kitten can still have an enjoyable time with the time whatever time they have left.

An adult cat has a more developed immune system. Therefore is better equipped to fight the virus with medications and regular trips to the vet.

Even so, a cat can live their whole life without contracting any feline leukemia related illnesses. Simply by managing it.

What Is Feline Leukemia And How Is It Spread

What Is Feline Leukemia

With the name “feline leukemia” many people are left with the impression that feline leukemia is a form of cancer. Feline leukemia also known as FeLV is unlike the blood cancer humans can contract.

It is actually a virus that attacks a cat’s immune system. It is an extremely contagious retrovirus. However, only felines can contact this virus, hence the name.

Even though feline leukemia is not cancer it can result in secondary infections and certain cancers. 

The risk of an outdoor cat contracting feline leukemia is high due to its contagious nature. The virus can be spread through saliva, blood, secretions of the nose, urine, and feces.

Feline leukemia can be spread easily through everyday sharing of objects like food bowls and litter boxes. As well as grooming, bites, and scratches.

It can also be passed on through a mother cat by nursing her kitten or may potentially develop in the womb. A cat that is positive for feline leukemia can spread the virus by doing something as simple as drinking from the same bowl as another cat. 

Diagnosing Feline Leukemia 

Feline leukemia can be diagnosed at the vet’s office by a simple blood test. This blood test is called ELISA. ELISA stands for enzyme-linked immunosorbent assay  The ELISA test is designed to find traces of FeLV protein in a cat’s blood.

The good thing about ELISA is that it can pick up early infections in cats. Another test is also used for detecting the virus. If a cat tests positive to an ELISA test, an IFA test is performed.

IFA stands for indirect immunofluorescent antibody assay. The IFA is used to figure out what phase of the infection a cat has reached and if they are at a later stage.

IFA is also used to confirm that a cat has contracted feline leukemia. Unlike the ELISA test, the IFA is sent out to a laboratory to be completed.

Unfortunately, if a cat tests positive to an IFA test, it is likely because the virus has advanced. 

Stages Of Infection

Once a cat tests positive for feline leukemia, there are different directions that it can go and progress in. 

Abortive Infections:

There are cases that a cat will contract the virus and their immune system will be able to fight it off. If their immune system is strong enough, the virus will be able to be completely eliminated from a cat’s body.

An abortive infection can happen however, it is extremely rare. It can only take place before the virus has integrated with the cat’s DNA.

Regressive Infections:

A regressive infection is when a cat’s immune system is able to fight the virus out of the bloodstream. However, in these cases, the FelV DNA is still present in the body.

That DNA is carried in a cat’s bone marrow. During this stage of infection, cats are not able to pass on the virus to other cats. Even so, if the virus is reactivated later in life they will be able to pass on the virus.

An estimated 10% of cases of feline leukemia are regressive infections.

Progressive Infections:

Progressive infections are cases where the FeLV traces are in the bloodstream. Cats with progressive infections may show signs and symptoms, and develop secondary infections. In these cases, cats are contagious and can spread the virus to other cats.

Treatment And Prevention

Treatment and Prevention

Since there is not an active cure for feline leukemia, there isn’t a set treatment plan. Even so, managing the virus and preventing secondary illness can give cats lots of relief.

Medications are prescribed to manage the illnesses that arise with feline leukemia. For example, antibiotics can be prescribed to help fight bacterial infections.

Cats that have feline leukemia should have two physical exams a year. Lab testing can help with managing by catching any problems that may arise.

There are methods to help prevent your cat from getting feline leukemia. The best way to prevent a cat from contracting FeLV is to keep them indoors!

If they aren’t in contact with any other cats this eliminates the chances of them getting the virus. Another form of prevention is for a cat to receive the feline leukemia vaccine.

The vaccine is designed to protect against the virus. However, it’s important to know that the vaccine is not a guarantee that a cat won’t get the virus.

Like any vaccine, the FeLV shot is not 100% effective. Revaccination of the vaccine is recommended by vets for a lasting effect.
