I’m about do get a new back door and need to supply the makers with a cat door. Anyone got any recommendations for one that is quite windproof (north facing) and also quite secure at keeping other cats out. We only have one large Tom who has broken a lot of doors. Tends to use his skull when he loses his magnet!! Help.
The one we are looking at is Sureflap cat flap with microchip identification. Any help appreciated
