This is like a state cavern for my hedgehog. I didn't really understand just how large this is but for bigger pocket pets like guinea pigs and hamsters, it's probably amazing. I stuffed this one with fleece strips and my hedgie will check it out but its too large for her to feel "safe" in so she prefers the smaller intimate space of a wooden bendy bridge. I would recommend a smaller size for a hedgehog but it is as advertised. The color is randomly selected so don't get your heart set on the purple you see in the main photo.
