I’m thinking about getting a pair of female mice, and want to keep them in a 10 gallon aquarium (I’ve heard of mice escaping from every wire gauge imaginable). I’m not exactly engineering savvy, and can’t figure out how to attach a water bottle in there since they’re all built for wire cages in mind, right? Velcro or a holder or something?

Same with hammocks and other level-adding items. I have a lizard hammock for my juvenile bearded dragon and that holds up… most of the time (fatty!)… with suction cups. Would that hold up to a pair of mice, or would I need some other alternative? I would want to be able to provide for my mice the same advantages of a multi-level wire cage while still keeping the added security.

Pics of your setups would be much appreciated.
I never said I was using sawdust. I was going to use kaytee softsorb or carefresh. I know about the phenol problems as well.

And I’ve heard from many rat/mouse sites that aquaria are fine, especially since mice can escape from just about any wire spacing, especially when young. That is from AFRMA itself.
Tank toppers are right out. At least the kind they sell around here. It has way too long of a drop, and the bars pretty spaced out. I can’t order anything online.
