How Tapeworms in Cats Spread

Cat owners sometimes find that their pets have been infected by an internal parasite; one common parasite is the tapeworm. Tapeworms are easily spread from one cat to another and also to humans. Understanding how tapeworms are spread can prevent and control contamination.

  1. Causes

    • According to PetMD, tapeworms are typically spread through an animal's ingestion of larvae. Eating an infected animal or chewing an item contaminated with eggs can also cause tapeworms to spread. Fleas can also carry tapeworm eggs, which can be ingested by a cat when it bites at fleas.

    Cats at Risk

    • Outdoor cats are at highest risk for contracting tapeworms, as they are more likely to eat rodents and other small animals that are infected.

    Symptoms

    • A cat that has contracted tapeworms may vomit, lose weight or have a bloody stool, according to the American Society for the Prevention of Cruelty to Animals. A cat with a severe case may appear pregnant, as it will get a rounded belly from the worms filling the digestive tract.

    Treatment

    • According to PetMD, a veterinarian will treat tapeworms with an injection or an oral medication. Some over-the-counter medications contain only laxatives that do not actually kill the worms. Veterinary care is the best method of treatment for tapeworms.
