[Detailed description] Step 1: Confirm the installation location of the door opening on your door. When looking for a location, you need to roughly estimate the height of your pet through the door opening (the average installation height is generally 10-15cm away from the ground). Use a ruler and pencil to draw the precise cutting position on the door along the paper film, and mark the cutting line on the door. Mark the relative positions of the 4 screw holes on the door (that is, the points of the 4 screw holes on the paper film) Step 2, take the four corners of the dotted line before opening, and use a 12mm rotor to open holes in 4 positions. Then cut your door with a chainsaw along the dotted line until the cut hole falls through the entire door. Step 3, before the formal installation of the door opening, put the cat door opening on the finished door opening and draw the actual position and the 4 screw holes drawn before. After doing these, you can install the cat door in the corresponding position and screw the 4 corner screws, and it's OK. (If it is a glass door, use a glass scratching tool to gently open it and fix it with glass glue:) Tools used: pencil, ruler, chainsaw, drill, screwdriver, tape measure, hammer, scissors, ruler,
