I'm so glad Princess is bonding with you this way, for her sake and for yours. Hopefully if she continues like this, she will be want less and less to go outside and will remain safe inside by her new found adorer. She really sounds like a sweatheart and I can see how it would break your heart to have to get rid of her after all those little signs of affection. Here's hoping the spaying does the trick and the others leave her alone so she's able to stay with you!
