Worms In Cats

There are several types of parasitic worms in cats. Roundworms, hookworms and tapeworms are important types of intestinal worms in cats that can also infect and cause disease in people. Lungworm, although not a risk to people, can lead to severe, life-threatening respiratory disease in cats. Read on to learn more, including the symptoms of worms in cats and how to protect your cat.

Types of worms in cats

Important types of worms to be aware are:

  • Roundworms in cats

    Roundworms are the most common type of intestinal worms in cats. The adult worms are long, spaghetti-like worms that live in the cat’s small intestine. Infestations are particularly common in kittens.


  • Hookworms in cats

    Hookworms are smaller than roundworms but can still cause severe disease. The adult worms attach to the intestinal wall and feed on blood with their sharp, biting mouthparts. Severe infestations can be fatal.


  • Tapeworms in cats

    Two important tapeworm species in Australian cats are the flea tapeworm and the cat tapeworm. Flea tapeworm infestations occur when fleas containing flea tapeworm larvae are ingested during grooming. Cat tapeworm infestations occur when cats hunt small animals which act as intermediate hosts.


  • Lungworms in cats

    Lungworms can cause significant respiratory disease in cats. The adult worms live in the cat’s lungs. Slugs and snails act as the intermediate host of feline lungworm. Cats get lungworm either by ingesting an infected snail or slug, or by ingesting a rodent, lizard or bird that has eaten an infected snail or slug

What do cat worms look like?

Occasionally, it may be possible to see worms in cat poop (or segments of worms in the case of tapeworms). However, specific tests are usually required to diagnose a worm infestation. For example, your veterinarian may recommend a test to look for microscopic worm eggs in a faecal sample.
