Hi all, we' ve bought one of those things with a suction cup that are supposed to make circular holes in glass but either it's rubbish, or we're particularly inept at using it, but all it's done so far is make a circular, and not very deep scratch! I did have my doubts about the efficacy of something that cost £15.
It's a single, fairly thin glass door that we need to make a hole in and I feel sure there must be some cat owners who have needed to install cat flaps to their properties on NVN, so hoped there's a local person who's good at it and could help.
I know we could buy a new full length pane of glass with a hole in it, but it seems such a waste. All and any advice appreciated.
