I am sorry Robyn, I know how much you are going to miss Tutter and how much he meant to you. He is such a sweet looking cat, but I have to agree with the others.
Your cousin has to learn that owning an animal is for LIFE, not to throw away at the slightest inconvience to her.
If she cannot afford to have her cat neutered than she should NOT get another one.
Does she not realize that she has most likely signed Tutters death certificate and she wants to get another one just like him.
What if something happens that she does not approve of with this kitty, is she going to send that one to the shelter also and then get another one.

I don't mean to make you feel any worse than what you do already, but as you can see, this has struck a cord and will strike a cord with a lot of us.

Maybe you should copy and paste these replies to your cousin in hopes that she doesn't make another mistake and sees herself as she really is. Not a very good cat lover.
