Many of us, even the staunchest animal activists, usually take it for granted that keeping a pet is morally acceptable. But regardless of how well we treat our animal “companions,” by keeping pets we are declaring ownership and paternal authority over other living creatures, and confining them to our homes. Is there any good moral justification for the keeping of pets? What makes some, if any, animals suitable as pets but not others? Do we have a special obligation to animal companions that does not extend to other animals?
