Jennie, I know this wasn't easy for you, but you did the right thing for Fred (I hope he doesn't have an identity crisis :p). The good thing is he is with family friends so you will get to keep in touch and PT updated.
I can understand some people not understanding why she decided to take him in the first place. But really you can't know the full impact of it until it actually happens. And at least she didn't just dump him off at a shelter. She found him a wonderful, loving home where he is obviously VERY happy.
I just love the second picture of him on the chair. :D
