Installation in Non-Glass Doors
Determine Pet Door Location
1A.
Measure and mark your pet’s shoulder height on the interior side
of door.
1B.
Determine location for the pet door. Draw a vertical center line
through the shoulder height line using a level.
If homeowner’s door or other application is
not level, the pet door must be marked level to
swing properly.
Prepare Door
2A.
Remove door by removing door hinge pins.
2B.
Place on a raised level surface such as saw horses. Place
interior side of door facing up.
Helpful Tip: Clamp down the door to prevent it from moving.
NOTE:
The Pet Door can be installed with the door hanging
based on your skill level.

2C.
Cut out template for Non-Glass Doors. Match the
marked lines on the door with the shoulder and center lines on
the template. Tape template in place and trace template. Make
sure to trace underneath tape and connect the corners.
Remove the template and any excess tape from the door.
When applying cutting template there
should be a minimum of 3” between the
bottom and sides of the door and the outer
edge of the cutting template to maintain
the structural integrity of the door.
Cut Pet Door Opening
3A.
Drill ½” (13mm) holes in inside corners and center of bottom
curve of drawn template.
Helpful Tip: Use both hands to hold drill steady and straight at
a 90° angle.
3B.
Beginning in one of the holes just drilled, cut along the drawn
template lines. After cutting out the opening, you may need to
recut to square the opening. This is necessary for the pet door
frame to t correctly.
Helpful Tip: Apply masking or painter’s tape on bottom of
jigsaw and outer edges of drawn template to protect door
nish. Use a le to remove burrs after drilling and cutting to
make cutting and installation easier.
Helpful Tip: Use proper saw blade length and type according
to door thickness and material (for example a wood blade for a
wood door and a metal blade for a metal door). Cut slowly using
both hands to hold the saw steady and straight at a 90° angle.
This will help prevent the blade from cutting unevenly between
interior and exterior sides of the door.
Make sure there is nothing underneath the door where
you will be drilling the holes or cutting out opening.

Fit Core Covers
4A.
Measure the thickest part (T) of your cut-out. Note this
measurement.
4B.
Depending on the thickness of your door, you may not need the
tunnel support and plastic core covers or the plastic core covers
may need to be trimmed for your installation. Use the “Plastic
Core Covers Cutting Guide” (Chart 1) to determine this. If you
are using the plastic core covers and tunnel support, go to Step
4C. If you are NOT using the plastic core covers and tunnel
support, go to Fit Check under Step 5.
4C.
Insert the long plastic core cover into channel of “U”-shaped
section of tunnel support. Insert the short plastic core cover
into channel of straight section of tunnel support.
4D.
Turn over assembled tunnel and insert plastic core covers
of assembled tunnel between frame posts and lip on ap
opening of exterior frame (frame without the ap). Tunnel
support should be facing up.
Optional:
Use duct tape in the corners of core covers to help
secure in place and to improve weather resistance.

Install Pet Door
5A.
Optional:
If the door cut-out thickness (T) is 1” (25 mm) or more,
insert the screw guides into the screw holes on the backside of the
interior frame (frame with ap and 4-way lock). The screw guides
help guide the screws through the screw holes from the interior
frame to the exterior frame.
Fit
Check
Before putting away your jigsaw, place the interior frame
(frame with ap and 4-way lock) inside the cut-out and check the t.
Then place the exterior frame (with assembled tunnel if needed for
your installation) into the underside of the cut-out to check the t. If the frames do not t
inside the opening, you may need to recut opening before proceeding with installation.
5B.
Before installing the pet door, you need to determine which screw
length is needed for your installation. Depending on your door
thickness, the screws may need to be trimmed with a hacksaw
or screw cutter. If the screws are too long, the nishing plugs will
not t. Use the Screw Selection Guide (Chart 2) to select which
screw to use and if it needs to be trimmed for your installation. To
trim screw, insert binder post onto end of screw to protect thread.
Using the binder post as a guide, cut screw to correct length with
a hacksaw. After cutting to length, remove the binder post to clean
screw threads. Repeat process with remaining screws.

Place exterior frame (with assembled tunnel if needed for
your installation) into cut-out from underside of door. Next,
place interior frame into cut-out aligning with exterior
frame. Insert binder posts into screw holes in exterior
frame from underside of door. Hold binder post in place
and insert appropriate length screw into screw holes in
interior frame.
Helpful Tip: Use saw horses, table or other work
surface to hold exterior frame in position while installing
the pet door.
Helpful Tip: Look through screw holes to help align interior
and exterior frames.
5D.
Use a screwdriver to evenly tighten screws throughout frame.
After tightening screws, check to make sure ap swings freely
and moves back to the center to meet magnet on bottom of
interior frame. It may be necessary to adjust screws to make
sure frames cover cut-out and the ap swings freely.
Use a manual screwdriver to tighten screws.
Do not overtighten. Overtightening can warp
the pet door frame.
5E.
Insert nishing plugs into screw holes in interior and exterior
frames for a polished look.
Optional:
Caulk inside threshvold where frames, core
covers, and tunnel support meet for weather resistance.
Training Pet
6A.
Rehang your door and begin training your pet. It may help for
you to be on one side of the door and your pet on the other. Lift
or tape open ap and try to talk your pet through the pet door.
After your pet has gone through a few times, allow the ap to
touch your pet’s back so they will become comfortable using
the pet door. If your pet will not go through the door, tape the
ap open until they use it on their own. Do not use the 4-way
lock until your pet is familiar with using the pet door.
Helpful Tip: Try treats or toys to encourage your pet to go
through the pet door and become comfortable using it.

Installation in Glass Doors and Windows
It is not possible to cut holes in tempered or double pane glass except at the
time of manufacture. Consult a professional glazier or glass manufacturer to
install the pet door in a glass door or window.
The Big Cat Door is also designed for installation in glass windows and doors. Cutting glass
is a skilled job and should be done by a professional glazier or glass manufacturer. To install
the pet door in glass, mark your pet’s shoulder height and location for the pet door using
instructions listed in Step 1 under Non-Glass Doors. Your glazier will need to cut a circular
hole with a diameter of 10
3
⁄8 ˝ (263 mm) with the center of the circle 1
13
⁄16 ˝ (46 mm) below the
shoulder height mark. After the cut-out is made, then the pet door can be installed using the
installation instructions under Non-Glass Doors starting with Step 5B.
Sliding Glass Door or
Window Installation:
If installing the pet door in a sliding glass
door or window, the pet door should be
installed on the inner panel with the interior
frame on the inside of the house so the
4-way lock does not prevent your door or
window from working properly.

skills, tools and materials (such as wood framing and hardware) will be required.
4-Way Locking System

and out of your home. Do not use the 4-way lock until your pet is familiar with using the pet door.
Knobs
Locks
In-Only: The in-only access option allows
your pet to enter the pet door but does not
allow your pet to exit. This access option
is useful at nighttime or if you need to take
your pet to the vet. To set the pet door to
in-only access, turn the right and left knobs
to the upright position with the locks inside
the ap opening.
Out-Only: The out-only access option
allows your pet to exit the pet door but
does not allow your pet to enter. To set
the pet door to out-only access, turn the
right and left knobs until positioned over
the interior side of the ap with the locks
positioned away from the ap opening.
Opened: Setting the pet door to the opened
position allows your pet full access in and out
of your home to come and go as they please.
Turn the right and left knobs to the upright
position with the locks positioned away
from the ap opening.
Locked: To keep your pet from using the
pet door, set the 4-way locks to the locked
position. Turn the right and left knobs so
both the knobs and locks are positioned
over the ap opening.
