I found some tubs at work that are only $5. They are 56q tubs. I was wondering how many female rats I could house in a tub that size comfortably. How many mice? I need 11 rats every week, of varying sizes. How many breeding females should I have then if I wanted to produce enough to cover that. I did some math and came up with 18 breeding females, getting 2 litters every week. I might end up some some surplus but I'd rather have too many than not enough.

Also, I might be able to get Mazuri lab block ordered in at a local pet store. I can get it online/delivered for $55 but I'm going to see if I can get it any cheaper here since they already order it in for their own rodents. I'm supposed to know tomorrow how much I can get it for. How long will 50lbs last 18 rodents. Give me an idea of how much a rat eats in a day (in grams). I just need to know what my feeding bills are going to be like.
