I'm so sorry about your kitty
You are NOT a woos! You lost your friend and companion of 20 years, and you have the right to grieve. Just take solance that you had many wonderful years together and she was no doubt very happy to have you as "her person". And when the time came, you had the courage and compassion to let her go on to a place where she will never again know suffering. You were looking out for her best interests to the very end; and were always a good friend to her. And I have no doubt that she knew that. God Bless, sweetie.
