I could use up 100+ mice a month easy. I have four ferrets (actually we are adopting my friends ferret today so that makes 5!) and they are on a raw diet. Twitch loves her mice.

I have several tanks but I was hoping to make some plastic bin enclosures with mesh on the side (for better ventilation) soon. Until I get that done though, I have tanks. For a 10g tank, or its equivalent, what size group should be housed in it?
