Jasper the cat/dog

We have 3 cats, one of whom is pretty sure he's a dog. Jasper (so named for the black and white smiling bear statue at the CN station in Jasper, Alberta) never stops wagging his u-shaped tail, follows the mailman along his daily route, and would stroll alongside our neighbours shnauzer when they would take him for a walk (sadly "Peppy" is no longer with us).
