We have an adorable 7 month old kitten. She has been spayed and signed off by the vet and absolutely LOVES going outside.
We have installed a cat flap which opens with her microchip for days we are out and obviously don’t want to leave windows open but she just isn’t getting it 
She will exit the cat flap with loads of encouragement every morning if I lift it three quarters of the way open but after I’ve opened windows etc she just uses them. She also doesn’t seem to understand that she has to push it with her head/paw to get out herself. Is it just a case of patience? We have had it for two weeks and I religiously spend time practising with her everyday but she just sits looking at me like I’m daft 😂 any tips?!
