>>>did you ever find the cat you fostered from a neighbour that moved?
Thanks for your enquiry, Chickensrock.
I had a new feline friend ('Patches') move in last October:

She just walked in one day, helped herself to a meal and curled up on my knee (and then slept on my bed that same night). Nobody knew where she'd come from, or had seen her around here before, and I didn't see any 'missing cat' posters anywhere.
She's currently sleeping in her cat house (a furry kennel type of thing) on my desk right next to me as I type, along with the four beautiful kittens she gave birth to this morning!
