Intestinal Worms in Cats: An Overview

Worms in cats are quite the common intestinal parasite, especially in kittens. Worms are so common, in fact, that your vet will typically test your cat annually via a stool sample.

Worms are intestinal parasites and may or may not cause visible signs of illness. Worms use your cat as a host in order to get nourishment, reproduce, and complete their lifecycle. There are a number of cat parasites, including a few major classes of worms.

Roundworms, tapeworms, and hookworms are the main types of worms found in cats. Fecal exam is the method of diagnosis and should be done during an annual check up.

Cats in the same household are also nice enough to share worm infestations with each other. Normally, if a fecal sample from one of the cats tests positive, your vet will want to treat the whole crowd.

Below is an overview on each of the major types of worms found in cats.

Roundworms - Roundworms (Toxocara Cati) look like spaghetti, and are usually only visible when vomited up. Kittens can become infected with roundworm via their mothers. This is the case even if the mother cat shows no signs of infection. The encysted form of the roundworm lies dormant in the mother cat, and is passed to the kitten. Usually, even if test results are negative, veterinarians will worm kittens 2-3 times to be sure.

In adult cats, infestations of this parasite severe enough to cause illness are unusual. This is because mature cats often develop a natural immunity against roundworm.

Hookworms - Hookworms hook themselves to the inside wall of your cat's intestines and hang on. Since they're tissue feeders, hookworms can cause blood loss, resulting in anemia. In addition, you may observe weight loss, intestinal illness, and poor hair coat. Most of the roundworm treatments used today will kill hookworms as well. Two or more treatments are required to eradicate this worm.

Tapeworms - Tapeworms consist of segments containing eggs. The segments drop off the worm, and along with the eggs are passed in the stool. They then dry out and begin to look like grains of rice and are fairly easy to spot. You'll sometimes see them in heavily traveled areas or around the cat's anus. Cats with these worms have been known to experience anal irritation and exhibit excessive licking.

It's important to control fleas. The flea ingests the tapeworm eggs and then your cat eats the flea. The tapeworm then lives in the intestinal tract of your cat and then produces, you guessed it, more tapeworms.

Usually, there will be no visible signs of illness in your cat from tapeworms. Remember that as long as there are fleas, your cat is at risk. Until you completely get rid of the fleas, a potential tapeworm problem exists.

Intestinal worms in cats can be present without any sign of visible illness. Since cat parasites put undue stress on your kitty, you should do what you can to keep his/her immune system strong. That includes not only regular vet visits, but also high quality food, regular exercise, and the room to explore.
