Put this sleepy cat door topper above the door frame or other places to trick your cat in to thinking theres another one taking a nap in his spots. The overall thickness of the model is around 9mm, however parts such as the legs and tail are only 2mm thick allowing you to place it on the frame and have the legs and tail dangle over the front side. You can play with the scaling to get your desired size/thickness though, no problem.
