This was a replacement for the one I bought several years ago. It’s so easy to put in and makes it so easy for the dogs. I prefer the stiff plastic door not a flap because of the wind blowing the flap so easy. This clear door also lets the dogs look in or out before going through the door.

Easy to use..except for my cats who needed a training session. But they're getting it now. I'd suggest having someone with a real tool set install this, but it's very easy once you get the hole cut in the door

Easy to install & the perfect size for our big guy.

Great cat door! Easy install , looks and works great!

Freaked my husband out as it is clear and looked like an open hole, however all the cats and my husband have gotten used to it.

Love the Tubby Cat, cat door. Perfect for my hefty boy.

My handyman installed it in about 15 minutes. Good size for my 11 lbs. cat. Good that the door is clear. A minor problem is that the magnet is a little too weak, preventing the door from closing completely...mainly stays open (a bit) on the lock side. My cat figured it out in 24 hours, even though going OUT drops down 3 steps.

I bought this set-up as a replacement for a door I have not been able to replace. The opening is larger than the last one, but the template included will make it easy to enlarge to the correct size. The plastic control knobs may endure the activity, that is pending. In my case, I would like to keep the dogs out of the cat room and the litter box and food. Mine is used indoors, so if the knobs break, not the end of the world. However, it is nice to be able to secure the cats when work is being done on the house, so they don't go out the door with the carpenter!
