When I lost a cat once, I posted a sign and picture saying "If he is living with you and eating all your food, that's fine. I just want to know he's okay!"

And I got to see him as an only cat in his new home.

Diana, don't be afraid to check with your neighbour, just to make sure she's ok with it, and that you are glad she has a good home. Just reassure her you are not there to take her back!

Um...does that mean you have room for another rescue?
