De-worming
Cats are often infected with roundworms. Hookworm and roundworm infection may lead to a distended belly, and can result in poor growth, vomiting, diarrhea and chronic intestinal diseases.
There are many safe and effective products available to eliminate these worms. Your veterinarian can prescribe a suitable treatment and discuss your kitten's de-worming program with you. It is usual to treat kittens for worms at two-week intervals between five and 12 weeks of age, and then every three to six months for the rest of their lives. When you get your kitten, ask the breeder what treatment your kitten has already received.
Tapeworms may also be a problem, although they are not as common in young kittens. Look for tapeworm segments around the cat's anus or in the feces. These look like grains of rice, and might even move. You may also see a larger segment of the tapeworm, which will be flat and ribbon-like.
Cats may get a tapeworm from eating mice, which carry the intermediate phase of the parasite. They may also get it from fleas. So be sure to treat your cat for fleas if you notice any tapeworms. Ordinary hookworm or roundworm tablets are not effective against tapeworm. Ask your veterinarian about proper treatment.
