- Feline leukemia is a cancerous disease caused by feline leukemia virus (FeLV). FeLV causes diseases other than leukemia including other cancers and immunodeficiency. Cats may not start to show signs of disease for months or years after being infected with FeLV. Infection with FeLV is a major cause of illness and death in domestic cats.

(2) What are Retroviruses? Majority of the leukemia cells caused by retroviruses in animals are lymphocytic leukemias. The T-cell leukemias are the most predominate in the lymphocytic leukemias. The first, most recent leukemia in non-human primates is the Gibbon Ape Leukemia Virus (GaLV), which caused T-cell leukemia when isolated.

Facts About Feline Leukemia Virus Yet, exposure to the feline leukemia virus doesn’t have to be a death sentence; about 70% of cats who encounter the virus are able to resist infection or eliminate the virus on their own. How Feline Leukemia Virus Is Transmitted. Feline leukemia is a disease that only affects cats -- it cannot be transmitted to people, dogs, or other animals. FeLV is passed from one cat to another through saliva, blood, and to some extent, urine and feces. The virus does not live long outside the cat’s body -- probably just a few hours. Grooming and fighting seem to be the commonest ways for infection to spread. Kittens can contract the disease in utero or through an infected mother’s milk.

- Feline Leukemia is a disease caused by the Feline Leukemia Virus (FeLV). The Leukemia itself is a cancer of the cat's lymphocytes (white blood cells). What FeLV does is it produces an enzyme which permits it to make and insert copies of its genes into cells it infects. When it infects the white blood cells it suppresses the immune system.

Facts About Feline Leukemia Virus In this Article. In this Article. Feline leukemia virus (FeLV) is second only to trauma as the leading cause of death in cats, killing 85% of persistently infected felines within three years of diagnosis. The virus commonly causes anemia or lymphoma, but because it suppresses the immune system, it can also predispose cats to deadly infections.

Feline Immunodeficiency Virus (FIV) in Cats FIV is toxic to the cat's T helper cells (CD4) which is a type of white blood cell that is crucial to the immune system. FIV dramatically affects these white blood cells of the immune system by significantly damaging or even killing them. This is what causes the feline's immune system to gradually weaken.

The Truth About FeLV/FIV Testing â Feline Leukemia Virus (FeLV) The immune system normally protects the cat from common infectious agents (bacteria, viruses, etc) that do not generally cause disease in healthy cats. However, if a cat’s immune system is weakened, as with FeLV, these same organisms can cause disease – known as secondary or opportunistic infection.

Cancer in cats We do know that some viral infections in cats can cause cancer, and feline leukaemia virus (FeLV) is probably the best example of this. Fortunately, infection with this virus is now relatively uncommon in most places.owever, when cats are exposed to this virus it can infect the blood-producing cells of the bone marrow, and can lead to the development of leukaemia or lymphoma. Infection with feline immunodeficiency virus (FIV) , related to human immunodeficiency virus or (HIV) also on occasions can lead to the development of cancer.
