Query: Horribly misleading name!

This "guinea pig run" should never have a guinea pig in it. They will hurt themselves and be terrified. As to the product description alleging you can use it as a guinea pig "pet carrier," I can only assume that the people writing the description think people are idiots. Your pig will be scared and could hurt themselves in that little ball. Get a real carrier and never try to "give your pig a chance to exercise freely" in these balls. Really the name and description should just be changed to rat or chinchilla holder.
