Aww, It sure is sad to hear the news. I know how hard it can be dealing with the death of your beloved one. I deal with animal deaths everyday at work and it breaks my heart. But I tell you one thing, you did the right thing by putting her to sleep and not to suffer anymore. The older the dogs or cats get, they always have problems. Also.. when a pet is put down.. they feel no pain, no suffering. I'm proud of you for the chose you made or else Tiger would be suffering for a while. again.. I'm very sorry for your loss. Hang in there!
