Feline Leukemia Virus: Symptoms of FeLV

The feline leukemia virus (FeLV) is a highly dangerous and usually deadly virus that affects the immune system of your cat. Unfortunately, there is no known treatment that is consistently effective against this disease.

FeLV, being a retrovirus, is able to insert copies of its own genetic material into the cells of the cat it has infected. This disease has a variety of signs and symptoms, many of which may be common to other conditions or diseases.

Healthy cats, like healthy people, are attacked by organisms all the time. Most of the time, both felines and humans can fight them off. When your cat’s immune system is compromised, however, opportunistic infections and parasitic organisms are more likely to thrive and cause damage.

Secondary infections and diseases will cause problems with FeLV infected cats. These secondary infections and diseases make the symptom list for this illness quite varied. FeLV infected cats have a difficult time fighting off invaders, even common bacteria.

Initially, symptoms of FeLV may include blood disorders, fever, enlarged lymph nodes, and general malaise. It’s possible for some cats, however, to experience no symptoms at the early stage.

FeLV infected cats are susceptible to developing leukemia as well as other forms of cancer. They often will develop anemia as well, and about 30 percent of infected cats will develop tumors. Some cats may exhibit excessive thirst and urination, which is also common to feline diabetes and other conditions.

Additional feline leukemia virus symptoms may also include depression, weight loss to the point of emaciation, and diarrhea. Cats may also experience blood in the stool, jaundice, constipation, and chronic recurring infections.

There are two stages to this disease. Upon initial infection, some cats will fight off the illness and it will not progress to the second stage. Other cats will not be so fortunate and the disease will progress.

If your cat has FeLV that has reached the second stage, the only thing you can do is to treat the secondary diseases and infections, and attempt to strengthen the immune system of your cat. Unfortunately, the disease is usually fatal.

According to professional sources, FeLV infections exist in about 2 to 3 percent of all cats. Infection rates are higher in high risk groups. If your cat is not in a high risk group, chances are limited that she will contract the disease. Since the disease is transmitted through contact with infected cats, keeping your cat indoors and away from infected cats is a good preventive measure.
