Is it possible for a Dwarf Hamster and a mouse to have babies? Because one of my friends has 2 rodents that have a body like a dwarf, have a tail longer than a dwarf is supposed to have, but not as long as a mouse tail, and their faces look like a mix between mouse and dwarf hamster. Is it possible for Dwarfs and mice to mix? And what do you think about housing mice with dwarfs?? Thanks!!
