Cat Licking Underside Of Tail. He is an outside cat otherwise in good health. Bald skin is more prone to sunburn, frostbite or other environmental insults, he says.
A tail resembling a pipe cleaner reflects a severely agitated, stressed and/or frightened cat trying to look bigger to ward off danger. For example, disc disease can cause back pain so that your cat overgrooms a certain spot on their back, while a urinary tract infection or anal sac impaction may encourage excessive grooming of the genitals or perianal area. My cat has an open sore on the underside of his tail near the base.
