The dimensions of these doors are identical to the now discontinued 304 and 309 cat flaps.

The Cat Mate 234 and 235 cat doors are sturdy, plastic-framed products made to fit into doors and walls of virtually any thickness. The designs are compatible for doors that lead outside, as well as for those that access bedrooms, laundry rooms, and garages. The door features a magnet on the bottom of the flap to keep it in place when not in use as well as to prevent any outside air from entering your house. With simple instructions for an easy installation, your cat will be going in and out independently in no time!


Please Note: If you plan to install this product into a wall, you will need to purchase additional products.

If you are starting from scratch, you can purchase the Cat Mate Door and Wall Kit bundle here.

If you’ve already purchased the Cat Mate Door, you can purchase the 2” wall liners individually here. Be sure to purchase enough wall liners to fill the entirety of the space you’ve cut out.


Both of these products have the same installation process, however their functions vary.


The Cat Mate 234 is a two-way locking system, which features a color-coded tab that alternates between “Unlocked” and “Locked” at your discretion. This is a great solution if you want to keep you cat in or out during certain times of the day. This product comes in the color white.


The Cat Mate 235 is a four-way locking system, which gives you complete control over your cat’s accessibility. This means that you can manually switch the lock to Exit Only, Enter Only, Completely Locked, or Completely Unlocked. This product comes in the colors white and brown.



  • Rigid acrylic flap with a weather strip around the perimeter

  • Flap is a tinted opaque color

  • Magnet at the bottom of the flap ensures that flap stays in place after use and prevents outside air from entering

  • Durable plastic frame

  • Good product review by James
    5 5 Good product

    It was very easy to install. Very well made for the price. We also liked that it had the Locking features so that until we felt comfortable the cats would get in and out we could lock them in at night. It was also easy to train them with the door

    5 3 Cat door

    The cat door is great but the screws were to short. Two different sizes came in the box but I had to go to the hardware store so I could get longer screws. Went together fine after that.

  • 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.

    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).

  • 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 Cat Door


To Replace the Flap in a Catmate or Dogmate Pet Door

To remove the flap, you will need a strong but thin object like a screwdriver. You will place this between the flap and the frame, and brace it between the flap and frame to stretch the frame outwards just enough that the flap pops out. To put in a new flap, simply do this process in reverse! 


1. Position the template on the installation location and trace around it.


Tip: Make sure that the bottom of the template is about level with your pet’s stomach. You can place it lower if you would like. If you choose to place it lower, make sure that it is not too low that it compromises the structural soundness of the door/panel or forces your pet to stoop when in use.


2. Prior to cutting, make sure that the cut-out line is level. Using a jigsaw, cut along the inside of that line, and be very careful to cut that hole square to the door.


Note: The cut-out must be level and even for the pet door flap to swing freely and function correctly.


3. Dry fit the frame cut-out to make sure that the pet door is swinging properly. Then follow the recommended instructions for your door or material thickness.


4. Take a measuring tape and determine the thickness of your door/panel.


5. If you are installing your 234/235 door into a thinner panel, less than 1-¼”, it may be necessary to trim the interior frame (the one that does NOT have the swinging flap). Make sure to keep hands away from the blade and use a piece of wood to support the inside of the frame.


6. For doors/panels 0” - ⅞” thick:

a) Put the INSIDE frame (one without the flap) on the inside of the door/panel and mark the screw spots with a pencil.

b) Remove the frame and drill out the 4 holes to 3/16” in diameter.

c) Choose the appropriate screws from the ones included in the instruction packet.

d) Position the OUTSIDE frame (one with the flap) on the exterior and screw the inside frame to it, sandwiching it to the door/panel.

e) Put on the screw covers.


7. For doors/panels 7/8” - 2” thick:

a) Put the OUTSIDE frame (one with the flap) on the exterior of the door/panel and mark the screw spots with a pencil and drill them out to 3/16” diameter.

b) Screw the inside frame on interior of the door using ½” screws.

c) Screw exterior frame on the outside of the door with the ¾” screws.

d) Put on the screw covers.


8. Enjoy your new Cat-Mate 234/235!


If you have any other questions about the Cat Mate 234 or 235 installation instructions, please give us a call at (800) 826-2871 for assistance.


Q: Wat is the difference in 2way door and 4way door?

A: The two way only locks or is unlocked, where the four way can be set for locked, open, in only, or out only.


Q: Does this come with all the cat mate cat door instructions and hardware?

A: Yes, it will come with everything you need to install it, except the tools.


Q: Is there a difference between the Cat Mate 4 Way Locking Cat Flap with Door Liner and the Cat Mate 4 Way Locking Cat Flap?

A: They are actually the same doors, only the first model is just more descriptive letting you know that it does come with the liner.


Q: Can you use this on an interior door?

A:Thhe two way locking model 234 is actually the best cat door for interior door or wall installation. It's a simple design, but is still lockable and can be paired with tunnels for wall installs.


Q: Is the cat mate 4 way locking cat flap the same size as the 221?

A: No the 221 is slightly larger, however this is the same size as the cat mate 309 and catmate 304 which is discontinued.


Q: What tunnel section do I need for a Cat Mate 234 or 235 door to put it through a 7" wall and how many?

A: The Cat Mate 234 or 235 Manual Cat Flap and Wall Framing Kit would work for the tunnel sections and you would need 3 to put it through a 7". In this case as the 235 would frame out 2" on its own and the 3 sections would give you an additional 6" and you just trim down the extra.

Below is a table that outlines the liner requirement based on the thickness of the wall you are installing the dog door for wall in.


Wall Thickness

Liners Required

51-90mm (2-4")


100-149mm (4-6")

200-249mm (8-10")


250-299mm (10-12")



Q: Do you have Cat Mate 4 way locking cat flap instructions?

A: Each pet door ships with operation and installation intructions. If you want to know in advance you can find Installation instructions on this page in the Installation Instructions tab.


Q: I lost my installation manual, where can I find instructions?

A: On this page, go the Installation Instructions tab for detailed information.


Q: What Manual Cat Mate pet door should I order to get the locking 4 way flap?

A: You will want to order Model 235 which has a stock number os 03AM235.
