I am not trying to get rid of my kitten.
If you refuse to get rid of your kitten are there any consequences?
My dad will step on it and my mom is going to watch.
It's understandable to feel that way if someone tell you to get rid of a pet. Try to talk to your father and make him understand.
I'm putting them in their place, everyone hates the cat and thinks it is gross.
Well it sounds like you are just trying to protect your cat which is fine. Maybe talk to your parents and see if you can just give your cat away instead of your parent's killing it. Your parents really should not be threatening to kill the animal anyway.
