What other species take dogs into their homes? Feed cats and turtles, monkeys and parakeets, deer and ponies? Hide frogs in the bathroom sink, build plastic tunnels for gerbils?
Humans cherish their pets, give them dear names, buy them toys and warm cushions, snacks and rhinestone collars.
Perhaps swans take in ducklings, and sows mother kittens. There are wolves known to feed abandoned human infants. Perhaps many creatures have space in their hearts and homes for the wandering stray struggling alone.
