Tapeworms are flat, tape-like worms common in the bowel of most mammals, including cats. If your cat has tapeworm, you might be able to see segments in the cat’s faeces or in their bedding. They resemble small grains of rice, and may move.
Roundworms are the most common intestinal parasite in cats, and look like a white earthworm. Adult worms live in the cat’s intestine and feed on digested food. Although they are not infectious to other cats when they are first passed, they become infectious after a few days once they turn into larvae.
