He does stairs!

Ferrets, we've read, have no depth perception (because their eyes are on the sides of their heads), consequently, they don't judge distance well.

Rocket loves to explore our house. And me, being the indulgent ferret owner I am, sometimes let him. One of the days he was exploring the upstairs, he encountered this really scary thing... A drop off! After much deliberation -- about 2 seconds of walking back and forth at the top of precipice, he decided to try hopping off it, just to see where it went I guess. He repeated this process again and again...
...the whole way to the bottom of the staircase. I scooped him up at the bottom and took him back up. After I carried him back up, a bit later he tore down the stairs again. Apparently in taking him back up so quickly, I'd reassured him he NEEDED to be down there! There must be something great!

Almost any chance he gets he darts down the stairs...

He goes down a bit like this:
He hops down by the wall with the railing, the whole way to the bottom of the last strait stair, where he walks across to the other wall, and goes down.
It's funny 'cause I walk down by the railing and step over (but only to the center) when I get to the bottom of the straight stair, too! I do it so I don't miss the triangle stair. His reason? Insanity?
This is a rough diagram of his steps on the bottom stairs. After switching walls to follow on the last strait stair and hopping down, he follows the wall 'til he hits the corner, and realizes he can't step down there, walks over to the center of the stair and hops down, then back to the wall, and for some reason then has to walk back to the center of the stair to hop down to the floor. Where he is then free to walk over to the wall by the door OR dart off straight across the floor trying to make it to the kitchen before I can catch him!

He's such a hoot! He has this thing with following the walls. He'll only walk across the center of a strange room when he gets really excited! He seems to forget he likes the walls. When he stops hopping around, he runs back to the wall...

As a little note: I feel it's important to know that my ferrets do have their own room in our three bedroom house where they get to get out of their cage to play. I block off the doorway (or close the door) so they can't escape, and they get to play for hours. (In a perfect world they'd be supervised at all times out of their cage. They are. Sometimes.)
