I have a 2 year old female cat named Lola. I have had her now for 3months. About month ago I installed an cat flap, and Lola has mastered how to 'get back' inside house using cat flap, however she has not grasped how to 'escape' to outside world using cat flap. She sits at door and looks through cat flap, and if I open cat flap door she will disappear through it. But am tired of doing this, and I don't understand why she will not go through cat flap on her own accord, what is stopping her from doing this? She does not take cat treats, so I tried playing with her favourite toys around cat flap so she can get used to it especially smell and bleeping sound. This has worked, as I said before she will use cat flap to get back inside, but not other way around for some strange reason

Also, am looking for advice on how I can get Lola to do the toilet outside? I made mistake of every time she went into her litter tray and would pick her up and put her outside in hope she would do her pee/poo outside somewhere. this method failed, as she will run back in and dive into her litter tray

Any advice is greatly appreciated.
many thanks, Donna
