They can, but make sure it is one with a solid running surface, not one with 'bars', if that makes sense. The gerbil's tail can become trapped and damaged in those.
No, they do not, that is an adaptation specific to hamsters, not gerbils.
I think gerbils will more often because they are more curious than hamsters.
gerbils. especially Ginnie pigs!
some hamsters are bigger then gerbils e.g. syrian hamsters.
yes.
No gerbils are!! Though hamsters are quite cute!
yes they do
Exercise wheels.
No Rabbits are of the Family Leporidae and hamsters are of the Family Cricetidae.
hamsters have been smaller than guinea pigs and gerbils look like squirrels but smaller
Yes! In fact, ALL hamster food is made for Hamsters AND Gerbils! It is perfectly fine to give gerbils the hamster food, and also to give hamsters gerbil food!
I don't think so!
