I thought I would share my mice containers. They aren't the best but they work.
I used an Iris 16 or 17 qt tub and did the ventilation like i've seen on other threads. The food hopper is a bit small but it makes me check on them everyday to top it off. I use a Volkman Rat and mouse gourmet cause I can't find Mazuri locally and I think they seem to like the seeds, pellets and nuts kind of mix. There was a 1.4 mice in there but one female turned into a baby stealer so she got her own 6 qt and another female somehow got trapped behind a cardboard box hide and died. Still really don't know how that happened. Now theirs 12 babies in there that should be weened but I don't quite know when they are ready.
Heres the baby stealer. She has 7 babies of her own that are starting to eat the food by themselves. Like the hopper on this cage. I think I'm going to add more ventilation to both cages.
C and C welcome
