Kim, she is adorable!! What a sweet girl!!
I say when the time comes for your friend to take her home, you admit that you somehow "lost" her.
Cute picture of your cat as well!! Is that your cat's bed or one of the dogs that the cat claimed?
I gave some of the dog beds to my cats and they just love them, they are always sleeping in them which they never did at the previous house. I may have to go out and get another one just for them.
