Thanks. I thought about doing a DIY on it, but I didn't take any pictures while it was in progress. 2 new girls just completed their quarinteen period 2 days ago so there's 4 in there now. I'm kinda worried about the new girls though. One hardly comes out of the nest box, and one of the older mice bullies both the new girls. I have been keeping an eye on them and still have the quarinteen bin set up just in case I have to move the new girls out of there. I haven't seen her bother them yet today though so that might be a good sign. I'm keeping my fingers crossed. I'm thinking of getting another roll of the wire mesh and eleminating the aquarium, replacing it with another DIY cage, and using the plexiglass second level as the bottom to contain the bedding to help out with ventallation and give them lots of climbing oppourtunities.
