Though we do not have a cat in our household due to having an anxious dog, we have several neighborhood cats that like to sun themselves in our yard. Do you have any cats?

No, I don't have cats either.  I'm allergic, but I am intrigued by the species and their ability to hunt and catch vermin so easily.

Exactly, that is why I never chase them off. Ever since the cats have been around, I have not had a single issue with mice in the house.

I agree.  They hang out in my backyard and I believe it helps a lot.  They hear sound too faint or too high for the human ear like those made by mice and rats.
