What is feline leukemia and can my cat get it?
A. Feline leukemia or FeLV is actually a misleading name for an entire group of diseases, which may include leukemia (a blood cancer) or tumors. But more often, related diseases develop before the cancer does. FeLV is highly contagious and is passed from cat to cat by licking, biting, and sneezing. FeLV is a very serious disease that is generally, but not always fatal. It is generally preventable with proper vaccinations. It is the number one killer in cats and outdoor cats are at substantially higher risk.
