Adopting a "cross-fostering attitude" with your own non-human animal companions (pets) allows them a more complete family life while in your care. Encourage them to participate in daily family activities as well as special holiday rituals. Always make sure to take their own species-specific needs in mind, as well. Housepets look to you as their moms and dads, siblings, and family friends; once brought into your home, you are all they've got. They enjoy being involved and will jump at the chance to contribute, each in their own style.
