Hi all, thought I'd update. I was using litter tray liners but noticed she was getting her little claws stuck in the plastic so have now removed it. She now pays much more attention to her litter, she scoops all the litter into a mound and perches on it before doing anything and she is now covering her poo which she wasnt before, I'm happy that she is comfortable with the litter tray and she hasn't done anything anywhere else in the house. I'm still not comfortable letting her into the bedroom though, in the blink of an eye she can be up-pee-down, hopefully another few days of retaining her in a small area while nobody is home will enforce the litter tray. The first two nights we had her she was sleeping beside us and didnt wee I think it was when she woke up and we were still asleep that she decided this was a good way to get attention. Maybe I'm goign to have to look for a pet behaviourist or maybe I'm just going to have to accept that my cat pees on my bed and I cant get cudles at night
