So as the hamster runs, it goes up, down and around. It huffs and puffs up to the high point where it rolls down, having to keep up with the wheel that's now rolling downwards due to gravity. If it's off its game, it does that loosing its stride and spinning around thing.

Changing its speed as necessary as it goes up and around, this would be much more challenging for the more athletically inclined hamster.

Could be wall mounted, ceiling mounted or just on a desk for the smaller versions.

If I were a hamster I'd love this.

Quite a few humans would like it, too.

Quite bakeable.

If it were semi-enclosed, the track could extend well outside the hamster cage and round the room.
