Great woe in the passing of Caramon, but as it is said, all good things must come to an end. However, Caramon will always be remembered as the embodiment of Snooch. Kidney failure, eh? Where did Snooch's desire for all things alcoholic stem from? If Caramon imbibed it may well have contributed to his demise, but he passed on as happy as he could be, under the circumstances. He will live on in the comic, as long as you keep creating them.
I lived for a time with 2 cats of similar behavior, the first was a Siamese/mix and the second MUST have had Maine Coon blood. The townhouse resounded whenever Maximillian("Max") leaped off of the bed upstairs. Never experienced those cats marking anything out of the ordinary, altho' I did have to build a plexiglass pan/surround for the litter pan, due to Max's practice of standing up while relieving himself.
I found your comic about 2 weeks ago, and have caught all of the way up now. I cast a vote for you at TopWebComics each and every day. Now that I've caught up here, it is time to do the same with more than 2 dozen others that I found thru TWC and The Dreamland Chronicles. Keep flyin', stay shiny!
