These are tape worm segments. Cats get tapeworm from ingesting fleas when they bite at them.i have a 7 1/2 female neutered cat. Have been having a tough yr with fleas. Now i have noticed small tan worm like things on her bedding....HELP!!!
Revolution and Advantage II! Not sure if Frontline came out with one yetI found it interesting to learn that there is a spot on wormer. I will have to check into that. I'm sure you all know how hard it is to give a cat oral wormers
