I had two siberian dwarf hamsters. A brown one named Sam and a white one named Max. Max was an avid escape artist who quickly learned how to work doors and latches and managed to escape a few times until he drowned in the sub pump resevoir. I awoke to find Sam sitting bewildered in his cage despite the door being left wide open from Max.
They loved those crinkle confetti filled boxes. I never owned another hamster after them.
