as falling under human animal roleplay or transformation play as well. Peter Shaffer's 1973 play Equus tells the story of a young man who has a pathological religious fascination with horses, but this appears closer to zoophilia than pet play. Andrew Lloyd Webber's 1981 musical Cats traces a tribe of urban cats, and in 2007 War Horse used full size puppets to play horses on stage. Erotic scenarios Like much of erotic play and roleplay, animal roleplay in an erotic or relational context is entirely defined by the people involved and by their mood and interests at the time of play. It ranges from the simple imitation of a vocal "whinnying" of a horse to the barking, panting or playful nudging of a puppy, or playful behaviour of a kitten, to crawling around on all fours and being fed, or petted, by hand. To the greater extremes of dressing up as a pony in modified horse tack, masks, prosthetics and temporary bondage based body modification (such as binding the forearms to the upperarms and/or the calves to the thighs). Public participation in human animal roleplay is varied. A couple could inconspicuously role-play a pet play scene in public, which would look to the casual observer like one partner is merely stroking the other's neck. In the case of some BDSM fetishists, one partner may wear a dog collar with a leash attached. The reasons for playing such a character or animal can vary as much as the physical manifestations and intensity of the play. Some people enjoy being able to "cut loose" into a different, or more dynamic personality (see other variations). In some cases, pet play is seen as a loving, quiet cuddling time where there is no need for verbalizations and the simple act of stroking, rubbing and holding the other partner is satisfying or reassuring in and of itself for those involved. For others, there may be a spiritual side to it. Some feel closer to their animal totem, while others may identify with something akin to a deeper side or part of their own psyche (known as therianthropy). For still others, there is the experience of power exchange setup in a context or structure which they can accept. Some cases could be considered a type of animal transformation fantasy. They can have strong elements of exhibitionism, be totally enjoyed in the privacy of the home, or
