Awww, Annie is beautiful! If I don't sound insensitive and probing, why did you have to put her down? It's so heartbreaking to lose a little fur friend! When I had to have my Daphne cat (who was 15 and suffering kidney failure) put to sleep two years ago, it was one of the two hardest things I have ever had to do in my life. Absolutely gut wrenching....
I'm so sorry.
