Cat Mate Manual Cat Flaps
The 234 and 235 are plastic framed with a self-liner that serves to 'frame out' a hollow core door in a thickness range of 0" - 2". The liner also makes for a neater appearance in a solid core door.
The only difference between these two Cat Mate cat flaps is that the 234 has a two-way lock and the 235 has a 4-way lock.
The flap is a rigid acrylic with weather strip around the perimeter and seals quite well.
The Cat Mate 234 2-Way Locking Cat Flap and 235 4-Way Locking Cat Flap may be installed in walls using the Cat Mate 303 tunnel sections. Buy as many as needed--at 2" each--for the thickness of the wall. These are found in cat door tunnel sections.
Cat Mate has completed an upgrade program for these cat doors. Specifics will found on our Cat Mate Upgrades page.

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!
234 and 235 Cat Door with Door with Liner
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. However, then you need to make sure that it is not so low it is compromising the integrity of the door/panel and that the top of the pet door is not too low causing your pet to stoop when using it.
2. Prior to cutting make sure that the cut out line is level. Using a jig saw cut along the inside of that line and be very careful to cut that hole square to the door.
Tip: The cut out must be level and even for the pet door flap to swing freely and function correctly.
3. Dry fit the frames 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) Then 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!
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.
