Since we have just the one bathroom, we use a candle to help remove certain unwanted odors. That keeps things a little more civilized. Right now we're using a candle that smells like pumpkin pie, although normally I'd just get a vanilla one.
At any rate, Wally is thoroughly obsessed with the lit candle. He likes to get on the counter and just watch it. I hope he never gets too close, he could really singe his whiskers.
