Thanks to everyone for the kind words. Schatz' was a prince until the end. He passed away early Sunday morning and somehow, by the grace of god, the sun came out for a couple of hours that afternoon and the snow had all but melted, so we were able to give him a proper burial. Today, there's five inches on the ground and we're bracing for a second storm. It would have been terrible to have had to bury him this week.
I'll probably get another cat some day, but I don't think I'll ever truly replace this one.
