Please tell your mom I *see* her kitty surrounded by Light, safe and fed, perhaps even led to a new home.
Thirty years ago, when my last child was but two weeks old, I had to drive away from two cats I couldn't catch when we were moving. They had been drifting away for several months before, but it was still one of the hardest and saddest things I've ever done. I guess it's probably why I am so protective of them all now.
