How long before a gerbil gets the hang of using a wheel?
Wel i pout a weel in my gerbils cage and he got right on it. So maybe a few days if your gerbil is shy or scared easly. Just takes time i would say about 2 days to a week.
It may take a while, as not all pets like wheels; especially not at first. You can try placing him the wheel and hope he goes for it, I had to do that with my gerbil. They just hop out, but they get used to it. Eventually he got on it himself, and started using it. He loved it! What kind of wheel is it? If there are any slots in the wheel, the gerbil might not want to use it because his feet can fall through. If you don't already have a closed wheel, I would invest in one, if he isn't using the one you have.
Well i have 2 gerbils and only one seems to get the hang of using the wheel they have had the wheel for almost a year and i have tried every other gerbil safe wheel and the one gerbil just runs for a second or to and then flops around on the insidebut maybe your gerbil just dont like the wheel i have had a few gerbils who hate the wheels and will try to chew on them
