We're down here in SE KS. I'll just get this out right now: I hate cats. We used to have a heck of a problem with pack rats and mice. I used bar bait, traps and every other toxic rodent killing cocktail known to man. The only way I finally cured the rat / mouse problem was Picking up a couple of free barn kittens. They stay outside in the barn and keep to themselves. We feed them table scraps and a bit of cat food, but just enough to keep them around. I haven't seen a pack rat since we've had these cats. We haven't had a mouse in the house, either.
