I don't think anyone has come up with a cure or antidote for saying goodbye under any circumstances in a more dignified way. Well, let me just say, it isn't particularly dignity I'm seeking just a sincere emotion that you will be missed, you are gone but not forgotten,I will miss you terribly, you can never be replaced nor would I ever try.
We lost a cat on Christmas Day. He was a wonderful sort....I should know I have quite a selection to choose from. His passing was not our first...we have a cat sanctuary and we have lost a few. Each and every time it is not unlike this being our only cat. At the time, he is indeed all that comes to mind.
It is a loss damnit...no matter who. You continue to fill his bowl...how long will that last? You still see him on his favorite rug, or in his favorite bed. Is that to make our transition of his not being there less painful? I don't know but at times it does feel like he is still here.
I said my "goodbye" as he was being carried out to the car, I knew he would never return. And he did not. I carry his memory with me. I can look at photos, but dear Klondike you are missed. RIP RD
