The origins of animal roleplay and pet play are probably various and diverse, again depending upon the participants involved. However, its origins are certainly influenced by costuming, fiction, myth and legend, roleplay and psychodrama in their various aspects. Some of the earliest published images of animal play (especially pony play) are to be found in the work of John Willie, primarily in Bizarre magazine published from 1946 to 1959.
Some of the equipment that can be used in animal roleplay include leash, chain, bit gag, neck collar, bondage harness, catsuit, bodystocking, butt plug, muzzle, ballet boots, etc.
CULTURAL AND RITUAL USE
Non-sexual animal roleplay was a common and integral part of a ritual in many tribal cultures both in recent and likely prehistoric times, where a member (or members) of the tribe would take the role physically and often spiritually of an animal that was either revered or hunted. Examples of the former include many of the American Indian tribes and Arctic native peoples. Examples of the latter are evidenced by cave paintings. In 1911, Julia Tuell photographed the last Animal Dance ("Massaum") performed by the Northern Cheyenne of Montana.
