You can just see "trouble maker" in Zeta's eyes. Sounds like you certainly have your hands full. Be forewarned....once they discover the cat box, they don't forget it's there or the crunchie treats....ewww. I have mine in a laundry room w/ a baby gate at the door, I thought if I had the gate there awhile, Trace would forget about the litter box....NOPE. If that gate's down, guess who's checkin' out treats?
