Thanks for the replies and advice everyone!

SatanicIntention I will keep an eye on those holes. I drilled them quite near the top and the holes are drilled pretty tiny. If i notice any chewing (which I probably will....) Ill take your advice and construct a new cage.

Im not sure how much space they need. I snapped a couple pics to get a better idea of what I've got.





I wanted to ask you all if you think this is big enough. If it is big enough could i keep more mice in it? Since I will probably have to replace this soon does anyone have a recomendation for what size tub to get to keep roughy 15 mice in. My plan is to buy enough mice for the month at the reptile show. Possibly take a stab at breeding since ill have to take care of loads of mice all the time anyway.
