Introducing “The Travel Cat x Argylle” Limited Edition Cat Backpack, bringing the secret spy life to bigger boned floofs. Sporting the quintessential Argylle pattern in our favorite blue, this backpack has all the same structural features as our best-selling “The Fat Cat” Backpack, with just a little more intrigue for your not-so-average kitty. This breathable cat backpack with a bubble window is great for larger "big boned" cats, 2 medium sized cats (yes, you can use it for two cats), or lots of kittens. It comes with a bubble window & screen attachment that you can swap out at your convenience or when going undercover!
