Common Worms in Cats

Cats and kittens may be prone to several worm infestations. Worms may cause various health problems; therefore, it is recommended that cats be seen by a veterinarian any time the presence of worms is suspected.

  1. Roundworms

    • Roundworms are worms that resemble thin strands of spaghetti that can be found in the cat's feces or vomit. Cats and kittens affected by roundworms develop vomiting, diarrhea, bloody stools and pot bellies.

    Tapeworms

    • Tapeworm segments resemble grains of rice and are often found stuck to the hair near the cat's anal area. Affected cats generally do not develop any significant symptoms other than anal itchiness.

    Hookworms

    • Unlike the other worms, hookworms measure only 1/8 inch and are not visible to the naked eye. Affected cats generally develop bloody stools, dull coats, loss of appetite and weight loss.

    Considerations

    • Several other types of worms can be present in cats, such as whipworms, heartworms and lungworms, but they are much less common. Cat owners should have their cats undergo fecal tests once a year to screen for worms.

    Warning

    • Some worms in cats may be transmissible to humans. Roundworm and hookworm larvae may infect humans, particularly children, and may migrate to various organs, causing complications (such as larva migrans).
