|18 year old cat - she is losing weight|
Because of a geriatric cat's reduced ability to absorb vitamins through the intestinal tract, the senior cat needs more vitamins and minerals.
Also, reduced kidney function leads to a loss of vitamin B in urine.
However a high quality cat food for the geriatric cat will accommodate this change in dietary requirement.
Accordingly, there is no need for a vitamin supplement for the senior cat unless the cat has an eating problem when vitamin supplements can be discussed with a veterinarian.
However, there might be a consensus amongst cat health experts that antioxidants benefit the elderly cat.
Antioxidants most commonly used are vitamins E and C (and co-enzyme Q). The Cat Owner's Home Veterinary Handbook, Fully Revised and Updated (at page 509) says that, "you can safely supplement your cat's diet using an antioxidant product prescribed by your veterinarian."
