It depends. I wouldn't go more than a 1.3 personally because I hate having to clean cages too often. The less you have in a tub, the less urine and feces created therefore the less you have to clean the tubs. I know a breeder that keeps 1.3 rats in about that size tub and claims he only has to clean every other week. I am in a way doubting that

I would think you could go 1.5 in that size tub with 1-2 litters raised up to weaned size but I'm not sure about mice.
