We have put her a bed at the top of the stairs with her litter box and food. The door is still open into the store room if she wants to go back in, but hopefully she will now start to venture downstairs and start to meet the cats and eventually the dogs.
She is very friendly – 10/10 to Katie for winning her confidence. She has a non-stop Purr-motor, I guess she realises that she has fallen into caring hands. I have noticed that her ears are dark inside, so Katie and I will be putting her some ear-drops in for that, starting tomorrow.
