Lady Grey is dead. I miss her.
My mother noticed that she smelled bad, so she gave her a bath, and the smell stayed. The smell was coming from her mouth. From something inside her. So, she took her to the vet. The vet said that her tumor was rotting, taking her internals with it, and she was in pain. The vet's advice was to put her down. My mother briefly considered calling me to come see her for a few minutes before she was gone, but decided, (correctly, as I see it) to conclude her immediately. The vet gave her a shot, and my mother held and petted Lady Grey as she faded.
It's sad that she went, but she went peaceful, and as comfortably as she could.
