Can hamsters and mice live together in the same cage?
Yes. Mine do. Rodents of different species can be kept in the same cage provided certain steps are followed. It is usually, not always, easy to mix newly weaned rodents. If you mix them when they’re grown, they’ll fight even those of their own species. You can try the split cage method for mixing adult rodents. This takes time and will test your patience and has a high failure rate. Hi kellcoss, your rodents are probably having sex. My male mouse and his wife, the dwarf Campbell hamster, have sex. They’re not compatible genetically though, so don’t expect a baby.
