Please recommend me an easy to install good catflap!

Just that really, we're not home during the week and would like the cat to be able to come and go as she pleases, I'm looking at microchip ones but is that really needed?!

Unless you want all the other neighborhood cats in your house spraying, fighting, eating your cats food then yes 100% need a microchip one!

Yes definitely get a microchip one otherwise you'll have loads of cats popping in and fighting and spraying everywhere and eating all your cats food. We have the battery one from petsafe (I think!) and it works really well.
