Yes - I am definitely going to be buying a freezer for mouse storage.
A portion of those mice are not mine - I split an order with a friend.
But I definitely am buying a freezer just for rodents. Last month - the starter relay on my fridge died, and while it was a quick repair, the mice did partially thaw and refroze, making it a PITA because they stuck together. So having a separate rodent freezer will not only make life easier, but it will give me a backup solution should one of the units fail in the future (IE I can put food in rodent freezer or rodents in food freezer) to reduce how much I have to try to keep cool in ice chest until repair man comes.
