“The Fat Cat" cat backpack is our international best-seller! It holds the most weight on the market — over 20 lbs of cat. Now in Deep Rose Pink, to keep your kitty stylish and safe. Our breathable cat backpack is great for larger "big boned" cats, 2 medium sized cats (yes, you can use it for two cats), or lots of kittens! All of our styles have a clip and bungee for you to attach a leash so your cat can "hang out" of the backpack. Many of our cat backpack styles, including "The Fat Cat," are airline approved.
