This is excellent news. We were also able to get our feral mother to come into the house, just by leaving the door open. We have a cat flap now and the cats all have access to the garden, but before we installed it, I used to leave the door open at night and Jessica (feral mum) would come into the house and hide behind a piece of furniture to allow me to go and close the back door. She very quickly appreciated the comfort of a warm bed at night and food whenever she wanted it.

That was seven years ago now and although she is never going to turn into a lap cat, she does trust us and definitely likes being around.
