Fit up to 12 lbs, Space Capsule Bubble Window Pet Carrier Backpack for Kitten Bunny Rabbie and Small Puppy Grey This is a used pet carrier backpack. My cats hated it so much that they marked it to let me know they hated it. I have cleaned this up as best as I can. The fan, I cannot find. Please replace the fan. Do not put your pet in this without it because they could get overheated. The middle panel zipper gets stuck. So if you want to turn this into an outside tent, the zipper will give you issues.
