Determining a Robo Dwarf Hamster's Age

Question

So when I bought my Roborovskis from PetSmart, they never really told me how old the hamsters were. Just wondering, how would you most accurately determine Robo hamster's age? Like, size, weight, whatever?

Answer 1

Well, I'm sure if you took it to your vet, they maybe be able to tell you an estimate age.

I bought my hamsters and they were only a couple months old.  

Answer 2

If you just bought them from PetSmart, I'd say 2-3 months old.  In robos, there is really no way to tell.  They are so small, they don't grow much except their first 2 weeks or so.
