My son was in college and volunteered at a no kill cat shelter. There was one he was attached to, and vice versa. Every time he arrived at the shelter, the cat would start meowing and crying. On graduation day, he adopted the cat. His name is McDee, as he was found near a McDonald's, and he's now about 15 years old. He is a great cat and he's very good with my two grandsons. I really do believe they know when they've been saved.
