Im so sorry about your Andwee. I can't imagine having to go through an experience like that. She was a beautiful kitty and obviously very loved.I had a shoulder kitty, too, Andwee (or, "Anduille"). She got eaten by a coyote after she refused to not heed the call of the wild, and slipped outside one night, in spite of my efforts to stop her. RIP.
My Little had mammary cancer which had spread to her lungs. I had to make the decision to say goodbye 10 weeks ago.
I hope we see them again someday.
RIP Andwee & Little
