Catty - not only would I like to do that with the Dad but also with the momma cat. She's not mine either. I'm not sure if she belongs to someone or is a stray.

As for putting a note on Dad that would require being able to touch him which has yet to happen. He won't let me within 10 feet of him. The momma cat is even worse, runs at the site of me in the window. Very frustrating.
