If my boxer x stayed outside all the time, rats would starve in their holes. He can sit there for hours waiting for one to emerge. I doubt many but a starving or very playfull cat would bother doing that.I would think a rat terrier would be better if you're looking for something to control rats. They're bigger and will fight a big rat(a cat won't)Dogs pursue them and dig them out of their tunnels.Cats just wait for one to come along and grab it.
