Cat Mate 221 Large Cat Door
- The most recommended large cat/small dog door
- Fits materials 0"– 2" in thickness, great for storm doors and interior/exterior installs

Product Details
The Cat Mate 221 is plastic framed and comes with its own self lining that serves to frame out a hollow core door in a thickness range of 0"– 2". The liner also makes for a neater appearance in a solid core door. It is large enough to accommodate the largest cat. The clear flap is a rigid Polypropylene with weatherstripping around the perimeter. The Cat Mate Large Cat Flap size incorporates a 4-way locking mechanism: maunally set to Locked, Unlocked, In Only, or Out Only as needed.
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.

Features:
- Versatile, four-way locking system (fully locked, unlocked, in-only or out-only) takes the basic pet door to the next level
- Made with a durable plastic frame and lined with brush weatherstripping for a weather-proof seal
- Magnetic closure prevents the flap from constantly swinging open and keeps the wind from blowing through
- Clear, Polypropylene 7" x 7" flap is easy for pets to see through and easy to clean
- Large flap accommodates the “fluffiest” of kitties—even those exceeding 20+ pounds! It also supports small dogs up to a shoulder height of 14”
- Installs easily in aluminum, metal, and hollow core doors, as well as polycarbonate, plywood, and other thin materials 0"– 2" thick
Benefits:
- Prevents active nocturnal cats from interrupting your sleep to eat or use the litter box
- For indoor installations, it allows you to put your litter box in a more convenient place to eliminate odors from entering certain parts of the house
- 4-Way lock allows you to control your pet's entry and exit

Worked Well
The Cat door was easy install and has worked well. Our cat is about 14lbs so the large door worked best for him. He was slow to want to go through it but a few treats a couple of days in a row and now he is a pro.
Great Product
Received product quickly. My husband installed it in our garage door without any problem and the cats starting using it immediately. We have eight outside cats that sleep and eat in our garage, so the door is getting a lot of use and so far so good.

Have 3 cats that use the door all the time. Would have given it 5 stars but occassionaly door doesn't swing all the way shut and I get a cold draft.
Nice door
Installed this door in a 2" thick panel of our patio enclosure. Template was exact, instructions clear but no 2 1/2" screws were included that are required when installing in a 2" panel. Fortunately Lowe's had brass screws.
