Well, it has happened to us as well. My older daughter found our baby red-sided in our master bathroom staring at the bathroom scale two nights ago. This led to the discovery of the lid of the snake cage (a 10 gal aquarium with a screen top) in my younger daughter's room being ajar.

The redsided is quite a bit more active than the pudget and the pudget is more likely to hole up some where. Probably still upstairs. On each of the 3 bedroom floors, I have placed a glass bowl, containing a minnow in water, and a desk lamp over it. so far no luck. Next step is to lower the house temp a bit, probably when we go away tor 2 days for Thanksgiving.

Hows that sound?
