We have had new doors fitted and have a working cat flap at last (the old one had the flap bit broken off so they would pop in and out the hole in daytime and I put a board up to keep them in at night ).
It's been two days and neither of my girls can work it out and just sit meowing pathetically to come in or go out. Any tips? I have pushed my hand through the flap both ways but the cats look terrified as if it's going to decapitate them and won't try it
