Hi there, Ratty_Ratkins! Yes, I am new to this forum. I got the idea of raising my mice on my desk, just based on the knowledge that mice are afraid of heights!
Ocassionally, when I had them first set up, maybe one or two would fall... but soon they stayed there..(although, I'd say its not that often you see one fall when you introduce them). On my desk I made them a wooden house, which I have polyerythaned to store it longer and so it would not absorb urine. As far as chewing goes.. there is hardly a problem-they dont chew their house..just the chewing toys and food I give them. If one were to chew the house, I would spray fooey on it (Fooey is the best animal deterent spray I have ever found, and boy is it bitter!!!!).
I will have to show you my pics! I promise to do that soon
