Full Answer

These symptoms depend on the type of lymphoma the cat suffers from. The mediastinal form is a type of lymphoma that attacks the lungs and the spaces between the lungs and their protective membranes. The alimentary form of lymphoma attacks the cat's gastrointestinal tract, while the multicentric form involves the cat's lymph nodes. The renal form of feline lymphoma attacks the kidneys.

Feline lymphoma is thought to be caused by the feline leukemia virus and the feline immunodeficiency virus. Cats who are most at risk for feline lymphoma are outdoor cats who haven't been vaccinated against either of these viruses.

Most types of feline blood cancers are lymphomas, or cancers that affect the cat's white blood cells. As of 2015, feline lymphoma is not curable, though the life of the animal can be prolonged through chemotherapy.
