I want to install a cat flap in an internal door that has raised beading in a rectangular shape, in two places as a decorative feature.

The bottom beading intrudes in the area that the cat flap should sit, plus the interior section of wood, within the rectangle, is thinner than the rest of the door!

To raise the cat flap assembly to clear the beading, makes the window of the flap some 10 inches from the floor.

Big question: would this be too high for a cat to use :confused:

Thanks in advance for any help.
