My condolences to all the other members that have lost a dear pet/friend/family member, in my case they were all three (most likely for others too).
I had to put my buddy (previous owner named her Infinity, the wife called her Finny, I just called her cat, or kitty, it didn't seem to make any difference, we were HER pets anyways) down on tuesday (10/16/2012). It was one of the hardest things to do, but she went downhill SO fast, there was no chance and it had to be done.
