Large Cat cave or litter tray (Penge SE20)

I bought this to use as a little cosy cave for my cat. She has absolutely no interest in it. Apart from today when taking it apart to photograph!! it is sold as a litter tray for large cats so could be used for either. Has space for a plant on top or storage for toys if preferred. Note it has never been used as litter tray so as new and very clean (Cushion or cat NOT included) measures 51cm diameter wide and 55 high
