Spend an afternoon on a pet door installation and make life easier for you and your pet long term. Customize pet door size for your cat or dog. Use the security panel to control access at night or in your absence. Pet door installation requires one person, but company is welcome and makes the work go faster.
Measure the height of your pet's chest to determine the correct pet door height from the floor/ground. If the ground outside is a different elevation from the floor inside, average the heights and mark the elevation with tape.
Run masking tape upward from the door's center bottom edge. Draw a perpendicular line up the exact center of the door to intersect the exact measurement for the pet door's bottom edge as measured and marked earlier with tape.
Mark the center of the pet door security cover/panel and align it with center of the exterior door marked earlier. Trace around the security panel with a heavy pencil, using it as a rectangular template for the pet door opening.
Drill small pilot holes through the corners of the pet door tracing. Keep the drill vertical. Re-drill halfway through the door with a larger bit. Finish the hole from the opposite side to avoid splintering the wood.
Insert the blade of a jigsaw into one of the corner holes and saw along the cut lines traced earlier for the pet door. Be particularly careful about cutting the corners neatly and completely at right angles. Remove the tape.
Run exterior caulking around the opening to make a water-tight seal for the pet door frame and prevent wood rot. Press the frame in place, remove excess caulking with your fingers, and secure it temporarily with painter's tape.
Position the interior frame of the pet door in the opening with the hinge side upward. Secure this inner panel to the outer panel with screws, effectively sandwiching the people door between.
Slip the security panel onto the pet door from the interior side to prevent your house pet from exiting or entering at night or when you are away from home. It5 also prevents other domestic or wild animals from entering.
Teach your dog or cat to use the pet door to exit and enter your home. If necessary, coax your reluctant pet from the opposite site with treats and praise it when it passes through the opening
