Sometimes as cats get older, they become lazy and don't groom as often. Maybe your cat isn't feeling well, try giving it some hairbal gel from the pet store. Possibly your cat is in pain somewhere and just can't reach the spots like it did before. Give it a bath on a warm day, make sure kitty gets totally dried off.
