Some of the most common types of worms cause symptoms that could potentially be fatal. The most common types of cat worms include ringworm, which live in dead skin, hookworms, tapeworms, roundworms, and whipworms. These types of worms live in the cat’s intestines.

Symptoms of worms in cats are pretty much the same as dog worm symptoms. Some are visible to the naked eye while others are not. One of the most obvious symptoms of worms in cats is the presence of worms in your cat’s stool. Your cat might have any number of parasitic worms in its feces such as the half-inch-long hookworm or a tapeworm. The tapeworm can reach up to a whopping three feet long if left untreated and it may have as many as 90 segments.
