How do cat worms get to your pet

Even indoor cats can get cat worms, so it is a good idea to know how do cats get them.  The most common form of infection is through feces infected with the worm’s eggs or larvae. A cat can step on feces and then lick their paws.

Outdoor cats can hunt a mouse that is infected with eggs. These then grow inside the cat, causing an infection. They can also be bitten by worm larvae penetrating the skin.

Types of cat worms

The most common types of cat worms are:

  • Roundworms. These are the most common and are shaped like spaghetti. The adult is usually between three to four inches long. One way of a kitten to get infected is through his mother’s nursing or by ingesting an infected rodent.
  • Hookworms are less than an inch long and are dangerous since they attack the bloodstream. This can cause anemia on the host. A cat can get infested via ingestion or skin contact.
  • Tapeworms are segmented worms that range from 4 to 28 inches in length. Cats can get infected by ingesting an infected flea or rodent.


Symptoms will depend on the type of worm. But the most common symptoms are:

  • Diarrhea
  • Vomiting
  • Coughing
  • Constipation
  • Bloody stool
  • Worms in the stool or a section of a worm sticking out of his anus.
  • Difficulty breathing
  • Bloating


It is very important that, if you suspect that your cat is infected with a worm, you do not medicate him. Some over the counter products can actually be harmful. Your veterinarian will determine the type of worm affecting your cat and will prescribe medication accordingly.
