Feline Leukemia - (FeLV) - This is a serious disease in cats caused by a viral infection. FeLV is also a complex disease, of which leukemia (cancer of the white blood cells) and cancerous tumors are only a small part. This includes:
FeLV impairs the cat's immune system much the way AIDS virus affects humans. As a result the cat has a lessened ability to fight off bacteria, fungi, and viruses.
FeLV is spread by direct contact with infected cats. It is usually transmitted in saliva, but low levels can be found in urine and feces. Food and water dishes, as well as litter boxes are a likely source of infection if healthy cats share with infected cats.
Feline Immunodeficiency Virus - (FIV) - More commonly known ad Feline AIDS (this is not the same as HIV in humans) is a potentially fatal virus disease that interferes with the immune system of the cat. The virus lives in the blood of the infected cat and is carried in their system throughout their life.
Cats that are infected with FIV can remain healthy for up to ten years. The symptoms are as follows:
FIV is spread from cat to cat primarily through bite wounds, as the virus is shed through high levels of saliva. The spread of FIV through food and water bowls as well as grooming is highly unlikely.
The only sure way to know if your cat has been exposed to either of these diseases is to run an FeLV/FIV screening test.
The only true way to prevent your cat from contracting either of these diseases is to make them a completely indoor cat.
