One of the things that hamsters and gerbils have is a wheel in their cage for them to run on. It hives them some exercise and a chance to have a run without leaving their cage.
So can guinea pigs run on a wheel at all and is it safe for them to do so.
Guinea pigs need to run as well and this could be a great way for them to get some exercise.
Unfortunately they can’t as they are not safe for them to go on. They don’t have the agility that gerbils and hamsters of and are not suitable for them to go on.
So it is best to steer clear of putting them on a wheel.
