Hookworms are common parasites that preferentially infect cats but can also live inside humans.

They are most often caught via contact with wet soil that has been used by cats or other pets for laying their feces.

The two most common in cats are Dipylidium caninum and Echinococcus multilocularis. E. multilocularis is transmitted to cats via the consumption of wild rodents and can infect humans if the worm's eggs are accidentally ingested.
