Birdcage Cold Weather Cover with Zipper, Insulated, Dustproof, with Zipper (M size 430x380 (zipper side) x 460 (height) mm) Used for about two days. I am selling it because I bought a different one since I couldn't attach a heater to the outside. The size is perfect for HOEI 35. The front has a zipper that can be opened. Thank you.
