What is Feline Leukemia

The feline leukemia virus is a retrovirus found anywhere in the world. Its diffusion is very unequal and will depend on factors such as the urban or rural environment, the rate of street cats, preventive sanitary measures regarding the disease contact between infected cats. Likewise we must say that any cat is susceptible to suffer the disease. It is enough to be infected by the virus. However the risk of infection is very variable and depends on the age of the animal, its habits, its state of health and in what environment it lives. Of course prevention through vaccination is highly recommended.

It is very important to emphasize that FeLV does not affect other domestic pets and does not interfere with the health of humans. So except for other cats, cat leukemia poses no danger to other beings.

The form of transmission is produced by a very close approach between the healthy cat and the infected  as it occurs with other viral diseases such as feline calivirus. In fact the virus can not survive for a long time outside the body of the feline. Feline leukemia therefore occurs through direct contact and exchange of bodily fluids.

Facts of Feline Leukemia

A very common way of passing the disease is grooming ( While licking each other to cleanse, saliva spreads to the healthy cat) fights or even occasionally, sharing feeders or drinking troughs. It is also present in breast milk, tears, urine and feces.

A mother can transmit the feline leukemia virus to puppies during the gestation period and later through the act of breastfeeding. You can even know how to tell if your cat is pregnant. The other habitual way of contagion can occur in fights through bites.

A retrovirus like this is a virus with genetic information in the form of RNA. However by invading a cell, it replicates in the form of DNA. The virus ends up penetrating the nucleus of the cell and mixing with its genetic material.

When this happens the virus multiplies and spreads through the cat’s bloodstream. In these initial moments of the disease, the animal can win the battle and end the infection. This occurs even in cats that have not shown any signs of having the disease. Some of the diseases can be cured by some medicines like benadryl for cats and other medicines.

However some cats have the bad luck that their immune system is not strong enough to kill the virus. These are the specimens that end up being persistently infected for their entire lives.

Feline leukemia life expectancy

After infection, it depends on each cat. The event can occur in months or years, this mainly depends on your cat growth, you see the cat growth chart and know about your kitten growth.

FeLV was isolated for the first time in the 1960s. In Europe it is estimated that the prevalence of the virus in healthy cats is between 1 and 5%. In sick cats this amount rises to 18%.

During 2000 scientists from Universities discovered that the prevalence of the virus in domestic cats in the urban area of ​​Madrid was 15%. Anyway in Europe, the figures are very different and we can find a fork that goes from 18% of healthy cats in Italy to less than 1% in Switzerland.

Feline Leukemia and Infection

We have to say that even if a cat comes in contact with the virus, it does not have to be infected. As with any other viral infection, its strength will depend on how the animal’s organism reacts. It can be a strong cat, fight the battle and win the disease. Even if there are diseases like fleas they can even be treated with cat flea treatment.

FeLV is much more fierce with puppies and older cats. Obviously it will also do more damage to adult felines that have low defenses, due to illness, medicine or anxiety. Once a cat has been exposed to the feline leukemia virus it can happen that it is immunized. About a third do it.

Another third removes the virus through urine or saliva, but remains latent in some organ. At any time it can be reactivated. But there have also been cases of cats that have eliminated the virus after several years. The last third will be infected for life. Some can continue with a good quality of life and others will develop diseases related to FeLV.
