- 24 Wood Screws
- 1 Long Wood Screw
- 1 Roll of Sealing Tunnel Tape
- 1 Tube of Silicone
- 1 Hole Transfer Jig with Level
- 1 Locking Cover
- 1 Cutout Template
- 6 Plywood Tunnel Pieces (4 for XL)
- 1 Inside Frame
- 1 Outside Frame
Tools
- Pencil
- Hammer/Mallet
- Measuring Tape
- Electric Drill
- Safety Gear
- Stud Finder
- Drywall Knife (or other for cutting inner wall)
- Saw for Cutting Outer Wall (compatible with your wall material)
- Razorblade (for trimming tape)
- ⅜” Drill Bit
- Philips Screwdriver
Step 1 Measure Your Pet
- Measure your pet and make a mark at least 3” above your pet’s height on your wall, this will line up with the top of the template.
- If a height taller than the max is needed, you will need to cut a new piece of lumber for your pet door tunnel.
Step 2 Prepare Wall for Installation
- Find a section of your wall that is against a stud on one side, but does not contain any plumbing or wiring.
- Extra-Large Size Only: This section will span from stud to stud for typical stud spacing of 16” on center (14.5" between studs).
Step 3 Make the Rough Cutout
| Wall Mount Template Dimensions | ||
|---|---|---|
| Flap Size | Width | Height |
| Small | 8" | 14-5/8" |
| Medium | 10" | 18-5/8" |
| Large | 12-1/8" | 22-5/8" |
| Extra Large | 14-3/8" | 26-5/8" |
- Line up the provided template with the edge of the stud and tape it to the wall. Trace the side of the template along the stud. Remove the template, then cut along the stud line with a saw.
- Line up the template again, adjusting to match the edge of the stud. Trace the remaining outline of the template. Remove the template and cut the rest of the lines drawn.
Step 4 Measure the Studs
- Determine the width of tunnel pieces to use by test fitting each width or measuring the width of studs inside the wall.
- For 2x4 studs, use the narrower (3.5”) plywood sections.
- For 2x6 studs, use the wider (5.5”) plywood sections.
Step 5 Insert the Vertical Tunnel Piece
- Screw the long wood screw halfway into the middle of the vertical piece to act as a handle. Insert the vertical tunnel section inside the wall cavity and tap into place with a mallet or hammer. The face of the plywood should be flush with the cutout. Add back any insulation that can fit under the cutout.
- Extra-Large Size Only: For standard 16" on center studs, the top and bottom pieces will span from stud to stud so you can skip this step.
- Extra-Large Size Only: For non-standard stud spacing, you will need to get wood from a local hardware store to create the frame for the pet door. The frame opening should match the size of the provided template.
Step 6 Install Corner Brackets
- Pre-install the four corner brackets at both ends of the two shorter plywood sections that match the width of your studs. The brackets must be flush with the edge of the short plywood pieces and centered.
Step 7 Install Bottom and Top Tunnel Pieces
- Insert the bottom tunnel piece and screw it into the existing stud making sure it is even with the cut edges and slightly angled down towards the outside. You may need a hammer/mallet to tap it into place if the fit is snug.
- Screw the bottom tunnel piece to the vertical tunnel piece, making sure the vertical tunnel piece is resting on the bottom of the inner wall for support.
- Use the long wood screw partially inserted into the vertical piece to hold onto it.
- Insert the top tunnel piece and screw it into the existing stud and vertical tunnel piece making sure it’s level and even with the cut edge of the drywall.
Step 8 Drill Through the Outer Wall
- Remove the long screw from the vertical tunnel piece.
- Using the provided transfer jig, drill ⅜” holes through the outer wall from the inside of the opening on the top-left and bottom-right corners.
Step 9 Mark Where to Cut the Outer Wall
- From the outside, line up the hole transfer jig with the drilled holes. Level the hole transfer jig and mark the jig’s corners on your wall.
- Using the template lined up with marked corners, mark all cut lines.
Step 10 Cut Outer Wall Opening
- Cut along the inside of the lines as accurately as possible.
- Trim up any areas that aren’t flush with the plywood tunnel. Clean the inside of your wall of any dust or debris.
Step 11a Prepare Tunnel for Sealing Tunnel Tape
- Make sure the tunnel area is clean and dry.
- To apply the sealing tunnel tape, start at the middle of the upper tunnel and apply the tape all around the tunnel, ending with a slight overlap at the top. Make sure to press the tape tightly into the corners as you go.
- Once in place, firmly apply pressure all along the tape to activate the adhesive.
Step 11b Apply Sealing Tunnel Tape
- Cut each corner up to the outer wall.
- Fold back each piece of the sealing tape against the outer wall, pressing firmly.
- Apply caulking to the openings in all four corners, sealing the cut area of the tape to the outer wall.
Step 12 Screw in the Frames
- Make sure the four tabs are upright and snug to the inside frame. You may have to loosen the screw to rotate it into place using a Phillips screwdriver.
- Insert the inside frame and level it in the opening with the hole transfer jig. While holding the frame flush against the wall, use four wood screws to screw the mounting tabs to the inside of the tunnel.
- If there are larger gaps you can pre-bend the mounting tab toward the tunnel.
Step 13 Install the Outside Frame
- Repeat installation step #12 for the outside frame, making sure the flap(s) swing through both frames without interference.
Step 14 Seal the Inside Frame
- From the outside, apply silicone in the tunnel, around the sides and bottom edges of the inside frame. This will seal the tunnel tape to prevent water intrusion.
Step 15 Seal the Outside Frame
- Use a sharp razor blade to trim off any excess tunnel tape that is sticking out past the outside frame on all four sides.
- Apply silicone where the outside frame meets the exterior wall on the top and sides, but leave the bottom open to allow for drainage.

FAQ
How can I tell if this will fit my cat?The simple way is to cut a hole in a piece of cardboard to the 6" x 11" flap size and see if they can get through comfortably. |
Is the flap rigid?No, the flap is flexible, it is just thicker than typical flaps. |
Can you see through it?It is kind of like a shower door, so you can see things through it, but can't really make out detail. |
Does it come with a cover to lock it?It does come with a cover that slides in on the inside. |
If this seals so well will it be hard for my cat to use?It is possible that you would need to adjust the magnets for training so check out our videos on this page for instruction on how to adjust those. |
Will this keep one pet in while letting another out?This is not an electronic door so any pets will be able to go in and out if they push hard enough. In addition, it will not prevent any stray and other animals like raccoons from getting in. |
What if my wall is thicker than 8"?The get the door mount version and have your contractor build the tunnel for you. |
Is the flap on the inside of the wall or outside?The flap is on the inside. And the pet door outside frame is designed so that the threshold on the bottom is lower than the one on the inside. This way if you do get any rain in the tunnel the water will evaporate or run out before it runs in. |
Can I get a double flap?We do have double flap doors, however, they are harder for smaller pets to push through so we don't really recommend them for cats. |
Is the door loud?It can be a little noisy when it closes, so it might not be the best choice for a bedroom if your kitties go in and out at night frequently. |
I live in an area with hot summers and cold winters. Is this a 4 season cat door?Yes! It has been tested in temperatures as low as -40° and as high as 110° Fahrenheit. |
