Well, I just voted for DaVinci because he is the one that I would keep if it was me. If your story is true then you would keep Caroline as a foster and she could stay at your house too. Kind of a two for one deal.

Maybe if you post photos of all of the kitties so we can see their beautiful faces then that would help us guess which one you chose.
(At least post a photo of MY DaVinci because I really want to see a photo of him whether he is the one you chose or not.)
