Chinchilla Exercise Wheels
There are several things to consider when buying a wheel for your chinchilla. First off, you'll need to get one that is much bigger than the kind you've probably seen for hamsters. And because of the size of the wheel and the weight of a chinchilla, we recommend getting a metal wheel rather than a plastic one. Metal will also fare better since chinchillas won't hesitate to chew plastic.
From a safety perspective, we highly recommend that the part where the chinchillas run be solid. That is, there shouldn't be any gaps for a chinchilla's feet to slip through.
Unfortunately, many chinchilla wheels are quite expensive. It took us a while to find a reasonably priced wheel that met our needs. We use the 15" model in the picture below. We've hooked it on to the sides of our cage and use a few zip ties to make sure it stays in place. Our one complaint is that this wheel can be noisy.
One product that we haven't had a chance to try, but that looks promising is the exercise saucer. It looks interesting because it provides an unobstructed view of your chinchilla.
