Doesn't seem to matter the species. Edwina goes up and down the staircase....a step at a time (albeit she prefers the side where it is wood rather than the carpet runner in the middle. ) Eddie, he jumps through the railing around the top of the stairs, landing on a step about one-third of the way down. He trots down a few stairs, then again jumps through the railing to the hallway below!

This morning I noticed Edwina with her ewwwww...digusting Eddie look on. I followed her gaze and there was Eddie drinking out of the toilet!

Boys will be boys!
