From Wowpedia
Aptly named 'ring bandits' by the pandaren, raccoons have dexterous paws and insatiable appetites for shiny objects, especially jewelry.[1] Some druids say pandaren and raccoons are distant cousins, but never when a pandaren can hear them.[2] There's a raging debate over whether tanukis are raccoons or dogs, but the distinction seems trivial when they're gnawing on your femur.[3]

Notes
