Reply to ZooCVT's Post: This is a project for biology class. We have to breed the dwarf hamsters and sell their babies. When we bought the hamsters, they were from the same family. They were together, but they didn't fight. Now she has her babies, and she keeps on chasing them around. I put her in the male cage, because I heard you shouldn't put the male in the female's cage. Hope this information helps!
