A long time ago thousands of years ago atleast, after man was created, in a lost record of history, a friend of humanity engineered what you know as "cats" and "dogs" as pets for us, these alien friends "look like humanoid cats and dogs". these beings come from other worlds, many myths were generated from these beings in folk lore. there are drawings of these beings on cave walls and other historic artifacts such as anubis. these beings are benevolent and have always been our friends, just two of the many races that have visited our planet. no other animals on earth are similar to humans, dogs, or cats.

they created the Canidae and the Felidae
