Misty has arrived. She came with her litter tray, toys, some food and scratcher. We let her out in the living room first and she had a look around then went behind the Tv for about an hour. I then managed to move the TV, pick her up and we've settled her in the spare room. She has all she needs there, water, food, litter tray and a nice bed in the corner with blankets and quilts, hers and Sunny's, a mix for some different smells. Sunny and Xavi have smelt some of her toys.
At the moment she has squished herself under the Computer desk, and is hiding away. I think in the night she may come out to have something to eat, we'll see in the morning.
She's a lovely cat, hasn't spat or hissed at us at all, and let us smoothe her when she walked past. She's just very intimidated and frightened right now.
I'll keep an update going to let you know how she's doing.
