I feel the best about rescues that need us the most. And, it sounds like Kitty really needed you right then.
Some of my cats won't go near anyone else, either. They have no reason to be afraid of anyone else, but I know that they will make themselves scarce if a vehicle even pulls up in the driveway.
I can understand Dd having this as 'her' cat. When I was a child, we couldn't have a cat because my father and sister were allergic to them. So, when a litter of kittens showed up at my cousin and grandmother's house, my grandmother let me pick the kitten that they would keep. There were white ones, and one orange tabby, which I chose.
I was allowed to name him. I chose Pumpkin. Even though he lived with them, his name was Pumpkin to the end, and he was 'my' cat, though I only saw him when I visited. :-)
Happy Birthday to little Kitty! :-)
