Morning all, I live in a 3 flat house with a common entrance door. The door is glazed with obscured bobbly wired glass. I want to put a cat flap in but I'm going to retain one of the panes just in case the council come a-knocking and instead put a replacement in. Is it possible for a supplier to provide the same type of glass with a hole in it? Or does it being safety, bobbly and wired mean it just isn't suitable for cat flaps? Any wisdom welcome. Cheers
