Please understand that this is handmade, so there may be some uneven stitching. Thank you for your purchase! The inside of the pouch uses cotton fabric that is difficult for sugar gliders' claws to get caught on (^^) There is cotton in the bottom, so it's fluffy (≧∇≦)b It's 18cm wide, 9cm high, and 9cm deep. It can fit 2-3 sugar gliders ٩(ˊᗜˋ*)و It can be attached to the ceiling and sides of both acrylic and wire cages ( ￣▽￣)ゞ Please wash by hand!! If you wash it in a washing machine, please put it in a net and wash it!!
