Our two rescued young cats will happily use the (new and expensive) cat flap whilst it is taped open. But they refuse to use it when they need to open the flap themselves. They sit outside sulking (and I'm terrified that they will vote with their paws and go find themselves a new home to live in).
So far we have tried to tempt them through with their current dried and wet food, and we are getting through packets of Dreamies very quickly.
Any suggestions please? It's fine to have the flap taped open in this weather but will be a bit drafty in winter!
