The Feline Leukemia Virus and Your Cat’s Symptoms
The feline leukemia virus (FeLV) has no known cure, and it has not been clinically proven that any antiviral or other agent will extend the life of an infected cat. This disease affects the immune system of cats, and is often fatal.
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.
Some cats will experience no outward symptoms during the initial stages of the disease. Early FeLV symptoms may include general malaise, blood conditions, fever, and swollen lymph nodes.
FeLV infected cats often will develop anemia. About 30 percent of infected cats will develop tumors. Leukemia and other forms of cancer are possible outcomes. Some cats may exhibit excessive urination and thirst, which is also common to other illnesses such as feline diabetes.
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.
Fortunately, if your cat is not in a high risk group, chances are limited that she will contract the disease. In fact, it’s estimated that only about 2 to 3 percent of all cats are infected with FeLV. Infection rates are higher in high risk groups. The disease is transmitted through direct contact with an infected cat. As such, keeping your cat indoors and away from infected cats is a good precaution and preventive measure.
