What worms in cats usually look like
The most common worm types in cats are roundworms, tapeworms, and hookworms. Some cats can also be exposed to heartworms, which are less common but much more serious.
Roundworms are often linked with pot-bellied kittens. Tapeworm segments can look like tiny grains of rice. Hookworms are harder to see but may cause weakness, dark stool, or pale gums in more severe cases.
How cats get worms
Cats can pick up worms in several ways. The most common routes are swallowing infected fleas, contact with contaminated stool or litter, hunting prey, or exposure through the mother when kittens are very young.
That is why indoor cats are not completely risk-free. Fleas and parasite eggs can still come into the home on shoes, clothing, or other pets.
