Every summer I take two weeks off for vacation and have a friend ferret-sit for me. During this time one of my boys loses a dramatic amount of weight only to regain it as soon as I return. I can only guess that this is because Mom is gone and they don't know what to make of the new person! I think it is probably more common than you think! I guess they love us as much as we love them!
