I want to install a catflap in our front door (no other possible place for it really). The door has two large panels so the catflap will have to straddle the frame and the botton panel. Anyone got a good way of filling the gap behind the catflap frame? I was thinking of 3d printing something to fill the gap and then just a think layer of sealant over the top. Or alternatively building a tunnel through the door and mounting the catflap frame to the tunnel face. But that could be quite bulky.
