Wooden frame and metal wire dog cage with a door and a top frame to prevent escape. 【Assembly/Disassembly】: Can be done by removing the four pins on the top corners without using any tools. 【No Tray, Alternative】: I placed newspaper, cardboard, and pee pads on the floor, and then placed a "slat" on top. I replaced the pee pads regularly. - Type: Dog cage - Material: Wooden frame and metal wire - Features: With door, with top frame (removable) - Size: For medium-sized dogs Some paint is peeling off the wooden and metal parts, so I will touch it up before shipping. Thank you for looking.
