Review on BEIKOTT Cat Backpack: Airline-Approved Transparent Pet Bubble Carrier Bag for Small Cats, Dogs, and Bunny - Ideal for Travel, Hiking, and Outdoor Adventures by David Chen

My budgie surprisingly seems to like this backpack. I like to take them outside for some fresh air and sunshine. She sits inside and chirps to the birds in the trees. Of course she would love to be with them, but that's the best I can do for her. You can screw the perch into the holes on the side of the bag and it works really well. It feels sturdy and the plastic is very clear with good visibility. I will say that it had a pretty strong plastic smell when I first got it and it lasted maybe a week or so. It's fine now, but I would suggest airing it out before putting pets, especially birds, in it. The straps are suitable for carrying a 36g bird but I don't know how they fit a heavier animal.
