Hi so I have 3 cats....thinking about getting a sureflap microchip catflap - the one with the app which you can control who comes and goes etc! Am I crazy for wanting to spend £150 on a catflap??? We have one Tabby who is driving me crazy wanting to go in and out at night - but we don't have a catflap at the moment so it's the door or the window we have to keep opening every 10 bloody minutes! Our other 2 we prefer to keep in at night - the Tabby can handle himself (caught him chasing a fox down the road the other night!) the other 2 not so much!
