They make regular visits to hospitals and nursing homes; wherever the calming presence of a dog, cat, or even a rabbit, will help patients get through whatever ordeal they are facing.
Since 2009, though, Furry Friends have been showing up in an unsual spot: libraries. Their job there is to simply listen to children read.
