Robo Dwarf Hamsters is considered as hard to handle. As per online reviews, it is possible to tame a Robo dwarf hamster by holding a handful of hamster food or treats by offering it to the Robo. You need to make sure that the Robo recognizes that you are offering it food.
No they don't make very good pets, cause you cant hold them very good, I have one not to long ago and I found out that they are just for looks.. You can't pet them at all!! They bit really hard also (found out that the hard way) lol good luck finding a hamster ? ;) but you can train it to pet an all!! or go with another hamster. ? lol
