Review on 🐾 Airline Approved Cat and Dog Carrier Backpack - Pet Carrier for Small to Medium Cats, Dogs, and Puppies up to 20 lbs - Travel-Friendly Cat and Dog Soft-Sided Carrier Bag - Convenient Pet Supplies Sling Carrier by Cristabel Logan

Tried it out with two cats to make sure it's a comfortable bag for cats. One of the cats weighs almost 15 pounds and the other around 10 pounds. There is no support below. So when you put the cat in the bag, it will gather in the middle part. Unfortunately I had to return this bag due to this problem. I think if in the future they have an updated version with support on the bottom of the bag I would buy them again because I appreciate my pet's comfort.
