Placing a cat door for window is not a viable option for many people. Include tenants or owners who do not want to cut into a centuries-old kitchen door. You can easily place a cat door in a guillotine window, allowing fluffy or the tiger to come and go as he pleases.
Lift the leaf from the window high enough to allow the pet door to sit comfortably in the gap. Estimate the height of the gap and calculate 4 inches. Measure the width of the window gap. This measure will be the width of the plywood. Cut the plywood to size using a square to obtain 90-degree angles. Inject the pet door into the section of plywood, following the guidance in your pet door kit.

Place the pet door mounted in the window opening. Close the window towards the top of the plywood. Measure the distance from the top of the window’s leaf open at the top of the window’s frame track. Cut two wooden dowels to size and place the dowels and in the window of tracks to prevent the window from opening from the outside. For a more permanent solution, screw two wood screws above the window (one on each side) on the tracks.
