The Cat Mate 234 or 235 Manual Cat Door for Walls

The Cat Mate 234 and 235 cat flaps are identical except that the Catmate 234 includes a 2-way lock and the 235 includes a 4-way lock. Both are plastic framed basic cat flaps with tunnel sections easily snap together to 'frame-out' a wall of any thickness. The flap is a rigid acrylic with weather strip around the perimeter and seals reasonably well. This is one of the easiest wall cat doors to install.

  • Good Basic Door review by Devine
    5 4 Good Basic Door

    Good cat door. It has clear see through flap and I opted for the four-way lock. The tunnel sections fit together easy and you can trim to fit to your walls thickness.

  • Great Product review by Texas
    5 5 Great Product

    Great Product. I have a 2" insulated garage door and was a little concerned about cutting the hole. I drilled a hole and used my jig-saw to cut VERY CAREFULLY along the template lines. Ensure the blade is long enough and be careful to keep the blade perpendicular to the door surface. The door fit perfectly and assembled easily. Still "training" the cats but I don't think there will be any issues. I used a medium large binder clip and a string to hold the door open to get the cats used to going in and out. The magnetic close seems to be fine. The only suggestion for the manufacturer would be to see if the lock mechanism could be improved. You have to push down in the center of the red tab with quite allot of force to move it to either position. The door does not detract from the appearance of the exterior. I'm pleased with the product and value.

  • Bought 3 of these and would recommend them review by ST
    5 5 Bought 3 of these and would recommend them

    These doors work great for both of my cats. One is very large and one is a small cat, but they both fit thru the door just fine. Got three - one to the garage and the other two so that they can exit the garage doors on both sides of the house. Priced right, easy to install and delivered in a timely fashion.

  • Excellent Product review by jon
    5 5 Excellent Product

    We looked a long time to find a door small enough to fit in the spot we wanted. This one was sized exactly as advertised.

    Worked perfectly. Good quality. Would purchase again.

  • Overall, a good product review by Yorkie
    5 4 Overall, a good product

    The product is well made an sturdy. The installation wasn't as easy as I had anticipated. The space between door panels that I needed to work with was barely large enough. The instructions call for a whole slightly larger than the product's frame. The tight fit caused the swinging door to misalign in it's frame; doesn't open/close properly. Still working on the problem

  • We love it and more importantly -- Abbey loves it! review by Nancy
    5 5 We love it and more importantly -- Abbey loves it!

    Our cat Abbey has always been good about trying new things -- and this cat door was no exception. We worked with her for a week -- offering treats, showing her how the door opened, etc. The most important tip we received was to make sure there was enough light so that she could see clearly on the other side.

  • Good product review by Another cat person
    5 4 Good product

    Product works great.
    The only comment I have would be to list the flap as some description other than "clear".
    The flap is not "clear" - it is "smoked" or "tinted" which is different from "clear". I would have preferred a "clear" flap to match the surrounding glass (I have it installed in a door with "clear" plexi-glass).

    I'm not a handy person and I put this in with hardly any frustration. It took a very short time. My cats got how it worked in a couple of days & it's a great investment.

    5 5 Cat door

    I love my new door to the screened in patio. I am free to go in and out as I want all day and night. I recommend the door to all cat guardians.

  • Correct the instructions review by Ronhar
    5 5 Correct the instructions

    The instructions about trimming the interior frame for the correct door thickness are flat wrong. Cutting the frame per the instructions made it too short to mate up with the exterior frame. Customer service provided a free wall liner to get the job done. Quality of the door is top notch - and love the product. Just get the instructions fixed or staple a "correction sheet" to the packing list when shipping the product.

    ed. note We'll check with the mfr about this issue and publish a correction on our product page if needed.

  • Needs some errata corrected in instructions review by wscott1943
    5 4 Needs some errata corrected in instructions

    I just finished installing my Cat-Mate 235W. Installation was fairly straightforward except for one thing. The instructions say to drill 5mm (3/16") holes to secure the door halves to the door. Since I don't have metric bits, I used the 3/16"drill instead. When I attempted to install the included screws, they proved too small in diameter. I had to scramble around in my spare screws bin to find larger screws to finish the install. The installation itself looked ok, but the oversize screw heads stick out like a sore thumb. There's just enough difference in diameter between 5mm and 5/16" to make the factory-supplied screws unusable. I recommend that anyone buying one of these to check screw diameters before drilling.

  • Doors good, cat skeptical review by Jon in Concord
    5 5 Doors good, cat skeptical

    I bought two of these and they are handsome additions to our home architecture. Nestled in the corners of the doors, all they lack is a small bottle labeled "Drink me" because if they had such, I'm sure every human visitor would scramble to get down to size and squeeze through.

    The cat was a different matter. She engaged in the most protracted pattern of approach and retreat that I have ever seen and it took her seven weeks to screw up the courage to use them. This despite dedicated coaching and the strategic placement of treats. However, in the end, she accepted the doors so I encourage patience for anyone considering this model.

    I had some minor questions during installation and the person who handled my call to the Help Line was able to straighten me out quickly. In the end, I'm quite pleased.

  • Good Door for All Size Cats review by Furry Friends Haven
    5 5 Good Door for All Size Cats

    I run a non-profit cat hospice and have had these doors for over 15 years. I've had to replace one complete door once and flaps a couple of times and it's very easy to do. (the replacements were needed because of damage that humans did to the doors and not the fault of the doors) .The initial installation was done by a handyman but it didn't look that hard. These doors are in hollow core doors and lead out into cat enclosures. Unlike the 210 door that fits through glass and screen, large cats don't seem to have problems fitting through this door. When I say large cats I am talking about cats over 20 lbs. If you are interested, you can take a peek at my review of teh 210 door and my woes with large cats. I have heard our cats slam through these doors at high speed many times with no damage to the door.

    America's Finest Pet Doors is a terrific company with great products, reasonable prics and wonderful customer service. Highly recommended!

Cat-Mate 303 Wall Liner Kit instructions:

1. Double check that you have the correct number of liners to frame out your wall before proceeding.

2. Next you will have to make a rectangular cut out in the wall. Take a level and pencil to mark the lines on the wall. The bottom of the cut should be level with your pet’s stomach or slightly lower. Check again that the line is straight and level before moving on.

Tip: It is very important that you not cut into any wall framing, electrical, pipes, etc. so double check when picking a location for the pet door.

Tip: The manufacturer recommends that you use wood to frame out the opening, and take note that the finished framed out opening should be 6-½” wide by 6-⅞” high.

3. Cut the interior hole out first and remove insulation.

4. Now drill holes from the inside through the exterior wall and use those as pilot holes for the outside cut.

Tip: Tape up the inside hole with plastic sheeting before cutting the outside wall. This will make clean up much easier.

5. Cut out the exterior wall.

6. Assemble wall liners and fit them onto the flap frame.

Tip: The manufacturer says that a firm push together will be enough to secure them together. You can use some glue to fit the liners together for a more sturdy installation.

7. Take the frame and screw it to the wall putting the liners through the cut out using the the ½” screws.

8. Now drill out the four screw holes using a 3/16” drill bit in diameter.

9. Put the exterior frame on using two of the 3/4” screws. Then place the hole covers and you are finished.

Click below to expand:

The CatMate 234 has a two way lock, so either it is locked or totally open. The CatMate 235 has a 4-way lock so you can set it for open, closed, in only, or out only.

Both doors are going to be recommended for more middle of the range, less extreme areas.

It you have a door or a window going through that same wall you can measure the jam and that should give you a good idea.

Of course! We sell the tunnels individually here

Yes, you can trim them if your wall is a little thinner.

The liners are only made in the white, but they are paintable.


The flap is a tinted rigid polycarbonate material, but you can still see through it.


Cat-Mate has theirCat Mate 221 model for large cats, but there are no tunnel sections so you would have to have the contractor build a tunnel for you to frame out the wall.
