  • Please Note: It is crucial to measure your wall thickness prior to purchasing a Cat Mate wall liner. You may need to purchase multiple liners depending on your wall thickness.

The 2" heavy-duty wall liners for Cat Mate Elite doors are used to frame out the wall where you plan to install your Cat Mate cat door. The Cat Mate wall liner creates a tunnel within the interior of the wall, so make sure they measure the thickness of your wall prior to purchasing to be sure that you order the correct number of wall liners. If your wall is 7" thick, you will require liners to frame up to 8" and trim it down (you would need 3 liners for 8", each liner adds 2" to your cat door's original 2"). The cat door itself adds to the framing range, so you will need to purchase liners based on the remaining amount of wall thickness after the cat door is accounted for. These liners are compatible with the Cat Mate 305, 306, 307, 355, 358, 359, and 360 models.

Note: For installation, washers are required for the placement of the screws. Washers are not provided in this purchase.

Installation Instructions

Step 1: Make sure that you measure the thickness of your wall and have the correct number of wall liners needed before making any rough openings in your wall.

Step 2: For the bottom of the cut-out, make sure that it is level with your pet’s belly to ensure comfort when in use.

Step 3: Next you will have to make a rectangular cut out in the wall that is 7” wide by 8” high. Using a level and pencil, mark the outside lines of your cut-out on the wall. Then check one more time that the line is straight and level.

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

Step 4: Now you will want to cut the hole out, by first cutting the interior wall and then removing any insulation.

Step 5: Next, drill holes from the inside through the exterior wall and use those as pilot holes for the outside cut. Be sure to remeasure on the outside for accuracy.

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

Step 6: Cut out the exterior wall.

Step 7: Take the pet door and remove the battery cover.

Step 8: Remove the interior frame cover entirely by taking out the two screws on the backside of the frame. Then remove the two screws that are under the battery cover.

Step 9: Remove the metal screw clips on the back using pliers.

Step 10: Take the wall liners and fit them onto the flap frame whose cover you previously removed.

Note: The manufacturer recommends pushing them together firmly, but glue can be used if you feel it would be more secure.

Step 11: The screw holes should be visible about halfway down the left and right side of the frame. You will need to put a washer under each screw.

Step 12: Take the frame and screw it to the wall, putting the liners through the cut-out.

Step 13: Put the inside frame cover back on using the screws you removed and replace the battery cover.

Note: Make sure that you do not trap any of the electrical wires.

Step 14: Finally, fit the exterior frame on using two of the 1” screws. Then fit the hole covers and you are finished.



What home improvement projects could I do to change the color of my wall liner and Cate Mate cat door?

If it's a paintable material, the exterior of your cat door can be painted to match the aesthetics of your home decor. You can also look into adding wood paneling or wall murals or other types of wallcoverings as a fun weekend DIY project. You can also stick wallpaper to the inside of your pet door tunnel with wallpaper paste to decorate it. However, we could not recommend adding unpasted or prepasted wallpaper liner as your pet's claws will cause noticeable wear and tear.
