Feline Lymphoma is one of the most common types of cat cancer. This type of feline cancer is usually associated with the Feline Leukemia Virus. Occasionally the Feline Immunodeficiency Virus has been implicated.
Feline Leukemia is the leading viral killer of cats today. The virus is spread by prolonged cat-to-cat contact and through bite wounds. The virus is shed in saliva, tears, urine, and feces.
