The Feline Leukemia Virus and Your Cat’s Symptoms

Feline leukemia virus (FeLV) is an often deadly virus that compromises the immune system of cats. There is no known cure for this disease, and to date, no treatments have been clinically proven to increase the longevity of otherwise healthy infected cats.

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.

Fungi, viruses, and bacteria attack felines and humans alike on a regular basis. Most of the time, a healthy cat or person will fight them off. With a compromised immune system, however, bacteria, parasites, viral and other organisms are more likely to do your cat harm.

FeLV infected cats have a difficult time fighting off infections and parasites. With a weakened immune system, your cat is more susceptible to secondary infections and diseases. The symptoms an infected cat experiences, to a large degree, are caused by these other diseases and conditions.

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.

Some FeLV infected cats may exhibit excessive urination and thirst, which is also common to a number of other conditions. They often will develop anemia, and some will develop tumors, leukemia, and other forms of cancer.

As the disease progresses, sick cats may present with more and varied symptoms. Blood in the stool, constipation, jaundice, and recurring infections may be present. Feline leukemia virus symptoms may also include and diarrhea, severe weight loss, and depression.

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.

Ultimately, for cats who reach the second stage of this disease, it is usually fatal. If your cat has FeLV, the only thing you can do is to treat the secondary diseases and infections, and attempt to strengthen the immune system of your cat.

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.
