I shed a few tears when I saw the picture of you and Simba. He reminds me of my "oldie may" dogs. As posted previously I have lost 9 in the past 32 years..........they were all a ripe old age. It hurts to let them go and it hurts even more to send them on their way but thank God you loved Simba enough not to let him suffer. He's waiting for you you know.
