cat burglar

Police in San Mateo, California don't seem to be too concerned about a rash of thefts, in which hundreds of items have been stolen. In fact, they even know who the culprit is but they're not planning on making any arrests, because the burglar is an actual cat.

When one hears the words "cat burglar", one might imagine a stealthy, nimble thief making his way into high rises to steal away the valuables of the well to do owner and vanishing off into the night. In this case, the words are literal. This is a cat. That burgles.
