 Please Note: The Cat Mate 221 "Large Cat Flap" and the Cat Mate 221 "Small Dog Door" are identical products except for the packaging (the part you throw away). Since the Cat version is available in brown and, currently, the Small Dog version is not, purchase the large cat version if you want a brown frame and have a small dog.
