Richard, I had that same thing happen to me once. A poor scared kitten was foraging in Don Pablo's Restaurant parking lot. I was so afraid that someone would come out, get in their car (while he was under it looking for food) and run over him. I left to get some food, and he was nowhere to be found when I got back. Like you, I now put some of my "discard" foods in the back of the van for just such an occasion!
