Leukemia (FELV)

Leukemia (FELV): This is a virus that is transmitted by direct contact with an infected cat, but is not transmitted from clothing, people or by air. It is not related to human leukemia, but does cause the immune system of the infected cat to break down. A cat may have the disease, but remain “healthy” and just be a carrier to infect other cats.

Symptoms:The symptoms may be difficult to detect because they develop so slowly. They include weight loss, fever, pale gums, recurrent infections, lack of energy, and loss of appetite.

Prevention: The only way to detect the disease is by a blood test. If the cat tests negative to the disease, it can be vaccinated. The blood test can be done on kittens three to four months old and the initial series is required, then an annual booster. If a cat tests positive for the disease, it must be isolated from other cats forever or be euthanized.

Treatment: The disease is terminal, but some cats may live a long life as a carrier with occasional cold-like symptoms that can be treated with nursing care. It is absolutely necessary that these cats be isolated from other cats. Once their quality of life has deteriorated, euthanasia may be the most humane course of action.
