so sorry for your loss
as "mom" to 3 cats, I was drawn to this thread and read thru it quickly hoping for a happy ending.
I lost 2 cats in 6 wks time in '08 and that was tough. I will forever miss those unique individuals that brought me so much love and joy. But in the months that followed, I was privileged to rescue 2 kittens needing homes. They have helped fill the void in my heart. I get tears in my eyes just thinking about how much I love them. The day my beloved Max died I just so happened to read Helen Keller's quote "When one door of happiness closes, another opens; but often we look so long at the closed door that we do not see the one which has been opened for us." It is so true.
When you're are ready, it would be a wonderful tribute to your lost kitty if you could open your heart and home to another kitty who desperately needs to be loved.
