I made a decision yesterday to say goodbye to a friend that I've known for nearly 20 years. It's one of the more heartbreaking things I've ever had to do. I've had my cat, Oreo, since I was a little girl. I love her, which is why I had to do this. She'd gotten sick and it was cancer, quick growing. So today, I let her go. The vet was very compassionate and has been over the course of caring for her. She went quickly and quietly and isn't suffering anymore, but I miss her desperatley. I know some people don't understand how people can get so attached to an animal, but well, you can. If you can't understand it, I'm not going to waste time explaining it. 
My whole family came to the vet with me, and my father made her a lovely little box in which to bury her. It made it easier having them all there. She really was a special cat...sweetest thing I've ever known. I feel blessed that I got to be her owner for so long.
That's really all I have to say. RIP Oreo. I love you
