Types of Worms in Cats

Roundworms, hookworms, tapeworms  and heartworms  are the most common worms found in North American cats :

  • Roundworms Adult worms live in the intestines and eat partially digested food. Roundworm larvae are also dangerous because they migrate through the body and can injure organs.
  • Hookworms Adult hookworms live in the cat’s small intestine, and they use their sharp mouthparts to dig into the intestinal wall to cause bleeding. They feed from the released blood.
  • Tapeworms Long worms resembling ribbon or tape, tapeworms have no mouths. They attach to the intestinal wall via suckers on their heads and directly absorb nutrients through their skin.
  • Heartworms Adult heartworms are less common in cats than dogs, but cats are still vulnerable to infection. These worms live in the heart and nearby vessels.

How Do Cats Get Worms?

Adult Cats Adult cats and weaned kittens most often acquire roundworms and hookworms from eating or licking soil or other material contaminated with feces from infected animals. Hookworm larvae can also enter a cat’s body directly through the paw pads or other exposed areas of flesh. Cats are usually infected with tapeworms after eating fleas containing tapeworm eggs. Less commonly, cats contract tapeworms from eating infected prey animals. Cats can also contract roundworms from eating prey. Heartworm infection occurs due to a bite from a mosquito that has already bitten an infected animal. The parasites enter the bloodstream through the bite wound.

Newborns and Nursing Kittens Both hookworms and feline roundworms can be passed from a nursing queen to her kittens. Hookworms can also cross the uterine wall to infect kittens in the womb.
