This is the roof panel for the Petio Dog Room Circle Regular. I purchased it to prevent my dog from jumping out, but I don't use the circle itself very much, so I'm selling it. I haven't used the roof for even a week since I attached it. If anyone is looking for the circle itself, please comment. I'm considering selling it since I haven't used it. As shown in the second photo, the cardboard box is partially damaged, but I will reinforce it with tape and ship it as is. Roof panel only (for Petio Circle White) Please make sure this is what you want. It's a beautiful item, but it's used, so please understand.
