B12 will support nervous system, GI system and immune system function. It may also stimulate a cat's appetite to some degree. B12 may be of benefit to cats with intestinal lymphoma. Since it is a water soluble vitamin, it is considered very safe to use. Discuss use and a dose with your veterinarian or a veterinary oncologist familiar with your cat's medical history and health status.
