Thanks, RTS! I will definitely look into getting some rodent repellant. I'd rather avoid the problem if I can.

I actually saw a mouse in my bedroom a few times a couple years ago, and I set up a humane trap - but never caught it. My cat, though, caught and killed several mice downstairs around that same time. He's good like that, LOL. Haven't seen any in the house since then. My cat is the reason why we can't get hamsters anymore - love me some hammies - cuz when they get out of the cage, it's unlikely that we'll see them alive again.
