My house has got mice in it. We've been hearing them in the walls, so my brother set traps out. All of the mice we've caught are very young so they're reproducing and we've likely got an infestation. Well, last night I could sometihng rustling in my trash can. I checked it out and found a tiny little mouse inside. I tried to move him into a tank, but he got away. :U But I found him again today! He was in my trash can again and I was able to move him into a makeshift habitat but now I don't know what to do with him. It's very cold where I live, so if I put him outside he'll likely freeze but I don't have any other options. I know that I can't domesticate him either, so what should I do? The mouse is currently in a 6 gallon tank with fleece, some nesting material, a bowl of water and some puffed millet that he's nibbling on. I've got the tank on a heating pad too since my room is in the basement and it's a bit chilly down here.
