conv: My girlfriend's cat is sick with Cancer. I don't think she's going to make it for much longer and I'm really shaken up by it. My girlfriend's cat is sick with Cancer. I'm so sorry to hear that. How old is the cat? Only a couple of years old. It's so upsetting to think that she won't make it for much longer. All you can do is make sure she's not in too much pain as she goes.
