If you are talking about how long can a robo dwarf hamster be pregnant then it will be about 6 to 5 months,also NEVER TOUCH THE BABIES, since the mom hamster will EAT the babies. I know, harsh.
Robo hamsters are robo hamsters, they can be about 2 inches long on average, and stay robo hamsters.
It depends. Well, I have four hamsters and three are robo hamsters and the other one is a Campbell dwarf hamster. Two of the robos are males and the other robo is a female. I put one male robo and the female robo together and they had 2 their first time. But the second litter and third litter, there were about 6-7 babies that were born. Usually the first litter is always smallest, but the most babies would probably be no more than 8 or 9, who knows, like I said, it depends. Oh and if your female is going to have babies, make sure the male is not in the cage with her or else she might get scared and eat her babies( she thinks she's protecting them).
