I don't have a cat flap, I'm renting and it's not a suitable area to let her out at night and she gets really panicky if she can't get in. I guess I could put cat biscuits in the living room with her water. I've put tin foil round the door handle as she doesn't like that so it might deter her from jumping and also I'll just have to wedge the door handle. I just cannot handle sleep deprivation on top of everything else. I'm self employed and if I don't work I don't have a roof over my head. I've hardly worked for a week, its torture trying to run a business on no sleep.
