I bought this for my rats, but it didn't fit their cage. I'm using a corner type instead. This one has been opened, but it's unused. It's made of ceramic, so it's hygienic as odors and dirt wash off easily. It's also heavy, so it doesn't move around, which is a good point. Hygienic ceramic toilet for hedgehogs! Width 200 x Depth 220 x Height 55mm ● This ceramic hedgehog toilet is easy to wash and prevents dirt from sticking. ● The entrance has a lip to prevent sand from spilling.
