Product would be excellent, if buying replacement flap was possible., 4/5/14
It angers me that I have to purchase an entire kit. I only need the flap. I will not purchase from PetSafe again....I will make sure the manufacturer has replacement parts available for purchase before buying any product.
It is absolutely unacceptable that I have to purchase the entire kit again.
No more PETSAFE at out house.

great door, but strong cats, 3/28/14
This is the second time the door has been broken when in locked position. Still no replacement doors???? Unacceptable!

Does the job but has drawbacks, 12/12/13
We have two cats, and I purchased this at Lowes for installation into the bottom of our front screen door. Although I'm a very experienced DIYer, I found the installation to be overly difficult, as it required 3-4 hands to get everything aligned and fastened together. Also, although I was careful about over tightening any fasteners, I still ended up with a cracked frame.

Once it was in, the door worked as expected. We especially like the ability to lock the door in a one-way mode in either direction. This is great when one cat has come in for the night and the second one is being bad and staying out late. The plastic hinges do creak after a while, and this can either be a good (you can tell when someone has entered or exited) or a bad (if you have active cats, it can drive you to distraction). A little WD-40 on the hinge posts solved the problem.

My other gripe with this unit is that it is not possible to buy a replacement door flap. The supplied door is quite sturdy, and I would never have guessed that I would need another. However, one of our cats hit it at full tilt while it was locked, splitting the plastic door in two and completely knocking it out of the frame. Fortunately, the cat seemed unperturbed by the event. In searching for a replacement, I found that the PetSafe site explicitly states "no replacement parts available, please buy a new door." This really is unacceptable.

PETSAFE RESPONSE: We appreciate the feedback on your experience with the Big Cat Door. We understand how needing a replacement flap when they are not available can be frustrating, but please know that we do offer loyalty discounts on replacement doors. To learn more about this discount, please contact our Customer Care Center at 1-800-732-2677

Works well but..., 10/22/13
Good looking door. Easy to install - finally got to use my rotary saw! Be sure to always lock BOTH the left and right sides of the door. My 17 lb cat has broken the plastic door twice when I got lazy.
