Safety Notice - Run-about Ball (by Super Pet) Do not use this product ever! I call it the 'Torture Ball', but many in the chinchilla community call it the 'Death Ball'. Get the picture? These balls do not allow air flow (despite the slits) and your chin can easily overheat. They are very unsafe for your chin. Your chin also poops and pees in them which means that is getting tossed around as he is moving around. The chin also has no control when in one of these and can bang into furniture or fall down stairs. For those of you who have one of these and think your chin likes it, well -- he doesn't, he is trying to escape from it. Throw it away and find a better and safer way for your chin to get exercise. This is another product that should be taken off the market.
