Iron Bess,
You have my deepest sympathy on the loss of your cat. I understand how much you loved and will miss him. He must have been very fortunate to be so loved by his family. I went thru the same thing with my 17 year old kitty in April and it was one of the hardest things i've ever had to do. I hope you can find some comfort to know that you are not alone in your feelings.
My sincerest condolences.
