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 with 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 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 a Cat Mate 303 Wall Liner for Cat Mate 234 & 235.
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 your 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.

Q: What is the difference in 2-way locking cat door and 4-way locking cat 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: The 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 Cat Mate 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.

Cat Mate / Dog Mate Warranty
3 YEAR LIMITED WARRANTY
Cat Mate / Dog Mate / Ani Mate guarantees your purchase for a period of three years from the date of original purchase against any defect arising due to faulty materials or manufacture. Accordingly any defective item will be repaired free of charge or replaced at the manufacturers option provided that the defect has not been caused by neglect, misuse or normal wear and tear and proof of purchase date is supplied. Your statutory rights are not affected.
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” - 7/8” 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.
