This is a bird deck that was attached to a heater cover. The heater cover is not included. The deck can be used on its own, but please be sure to check the size of the deck and the compatible cage in photos ⑥ and ⑦ before considering a purchase. *Please refer to photos ③ and ④. There are small brown spots on the deck itself, but this is not dirt. It is part of the material. There are also faint spots on the back. Thank you for your understanding. Please direct inquiries to the comments section.
