Best size for small cats and kittens, tiny toys, miniature dogs, even rabbits and other tiny furry friends! Many professional animal trainers and exhibitors who travel with cats and dogs extensively prefer SturdiBag because it is simply the best in-cabin, light weight, flex-height pet carrier available. Whether it is used on a plane, in the car, or for carrying by foot, your pet will be comfortable and safe in a SturdiBag cat or small dog carrier.
