I'm so sorry. It's wonderful that you had her so long. Hugs from myself and Diamond (and from Ootek, Finn, and Razz in critter Heaven).

I recently found an old cassette tape my mother had made of "mystery sounds" when I was in . . . maybe second grade (she brought it in to my class to see if we could guess what each sound was). It included the engine of our long-sold 1978 VW van and, at the very end, Razz purring. She was PTS in February of 2000 at 16 1/2, when she was blind, had heart problems, and finally refused to eat. Mom and I both started laughing and then cried all over each other.
