Feline leukemia is a transmittable virus that can damage a catâs immune system. It can sometimes be hard to spot because not all cats with the disease will show symptoms. The virus can be in a catâs bodily fluids including saliva, urine, feces, and blood, and can be passed through direct contact or even grooming.
1 Multicentric lymphoma - generally involves multiple lymph nodes and possibly multiple organs. This form is more closely associated with feline leukemia and the prognosis for this form is not as good, especially if the cat is feline leukemia positive.  Mesenteric lymphoma - very common in cats over 10 years of age. The intestinal form affects the small intestine but sometimes the stomach, leading to gastric lymphoma. This form is least likely to be associated with feline leukemia.
