Pet Space is going into a headspace of an animal and acting as that animal. Pet Space is different than Pet Play. Pet Play is the BDSM version of Pet Space. Pet Space is completely SFW and for all ages. Like in Pet Play there is collars, leashes, ears. etc. But activities would include playing with toys, going for walks, etc.

Pet Space is what you do when you're participating in Pet Play which is a form of BDSM. Basically, you act as the animal you describe yourself as. I.e., Kitten, Puppy, Pony, etc. This often involves Pet Gear as in ears, collar and a tail. And if you're sexual with it, cuffs and other kinky items. It does not have to be sexual role play but is adviced for people 18+.
