I am looking for something to put on the door used to enter the garage. Should I be concerned with energy efficiency? I don’t want let out the AC or heat!
Answer by ChewyFeb 01, 2018
This door is not airtight.

can you use this on a screen door
Answer by ChewyAug 18, 2017
This product has easy installation in all doors & walls. It's also recommended for very thin panels & screens, self lining to 2" thick.

Do I need a wall liner for this product?
Answer by ChewyJan 21, 2019
A wall liner is only needed when installing the pet door into a wall.

Is this cat mate door compatible with the cat mate wall liner?
Answer by ChewyDec 07, 2018
The Cat Mate Wall Liner (Ref. 303) is available separately through the manufacturer.

Not For Screen Doors

Extremely hard to install. Had to use a grinder top cut off most of inner frame. I guess this is made for thick wood doors as it has 2" of thickness. Almost impossible to use on a screen door. So many modifications it will probably never last long.

Good door for a large cat

Great price. Easy to install. Works well. Our four cats took to it easily. Small problem - the mounting hardware was very cheap; the heads broke off two of the screws and a third screw became bent during the installation. I felt like I was mounting a cat door using toy screws.

We actually broke it in 2. For an outside. At house! Use the part for a house door and hung some cut up table setting! Worked great for both! I’d buy again

Very Nice Cat Door for Wall

I purchased the Cat Mate large cat door to install in a 2x3 studded wall and finished with drywall and beadboard paneling on the walls. The directions on this site will tell you that there is no wall liner for this Cat Mate door but when I checked the Closer Pets website I found out that they are the same company and it will fit perfectly. I took a chance and it was made for each other. I ordered one Closer Pets wall liner and the Large Cat Mate cat door. Went together easily after cutting out both sides of the wall and screwing two short 2x3's in between the wall on both sides of the cutouts so that both sides of the cat door had something solid to screw into. Hardest part was making sure the two cutouts lined up well.

I have had this installed for about two months. There were a few instances where it locked itself, preventing kitties from getting to the inside room. Today, I broke it and threw it away because kitties were crying to get inside for food and water.

Perfect for my average sized cats.

I installed this in a plexiglass panel, added a frame that slipped inside the window frame and success! My cats now have access to their catio without asking, and I can remove it to open the whole window for cleaning. Please note: I am so glad I got the large (flap), as my average sized cats would not have had enough room to get through without touching the sides. The small one should be fine temporarily for KITTENS! (Plastic locks are difficult to slide, so hope they won't break. So far so good.)
