We had a kitten wander in here a year ago and the dogs let it stay (very surprising). It wore out the chipmunks around here. Unfortunately, cats are not at the top of the food chain, and a few days ago a pair (mating, I presume? Didn't think they hunt in tandem) of hawks taught him that lesson. The one was probably 16-18" tall...biggest hawk I have ever seen. Now we have a hawk problem.
