  • Patagonian cavies mate for life and are monogamous. Males will urinate on females to “mark” them and keep other males away. Multiple pairs will sometimes share a communal den.
  • They are very fast runners and can reach up 35 mph. Their hind feet have three toes with hoof like claws, and their front feet have four clawed toes for digging.
