Intestinal Parasites in Cats

Certain intestinal parasites--roundworms, hookworms and tapeworms--are very common in cats and kittens. According to Cornell University College of Veterinary Medicine, up to forty-five percent of all cats suffer from gastrointestinal parasites. Sometimes the symptoms are obvious and unsettling: your cat throws up a wriggling, white worm. Normally, signs are less dramatic. Vomiting, diarrhea and a pot-bellied appearance can indicate the presence of worms.

  1. Roundworms

    • Most kittens have roundworms, transmitted by the mother cat. Left untreated, roundworms can cause severe illness or death in kittens. Normal deworming protocols will eliminate this common worm.

    Hookworms

    • Hookworms are more common in cats living in hot, humid areas. Acute hookworm infestation can cause anemia and diarrhea. Treat with the appropriate dewormer.

    Tapeworms

    • Tapeworms are the most common intestinal worm in cats. Tapeworms are transmitted by fleas or by consuming raw, freshwater fish or dead animals. It can spread via contaminated feces.

    Whipworms

    • Whipworms are common in dogs but less so in cats. Spread by contaminated feces, whipworms cause anemia and diarrhea.

    Flukes

    • Flukes are flat worms acquired by eating raw fish, shellfish or frogs. This is a rare condition and treatment is more complicated than with other worms.

    Prevention

    • Test your cat regularly for parasites and deworm accordingly. Over-the-counter dewormers are available, but prescription products are more targeted and effective.
