Instructions : Draw your kitties door lines then carefully score the lines. Continue to score and cut through with the special scoring tool/cutting tool. We suggest you wear gloves to protect your fingers and hands.

Cut the container 3 ways leaving the top part nearly cut through but not all the way throughit will form a hinge. Use a hair dryer to help soften the plastic and to prevent breaking the box. Slowly bend the top part to make it like scaffolding above you as seen during construction. Then use duct tape to help hold it up that upper flap and stabilize it. Cover all sharp cut edges with duct tape also. Please refer back to our video to see how it was done.

Using a hinged door at the top is another idea for making a swinging door instead of holding it up with duct tape.
