I'm going to tell my parents to stop threatening to give my cat away
I'm very concerned about this. Why are they threatening to give away your cat?
The cat is misbehaving, but I love them.
Dont feel bad about sticking up for your cat because you want to keep it. This is the only way your family will know how much you care about it.
Fine, I'll give it a shot.
If your parents decide to not give the cat away then you should promise that you will not neglect the cat and take proper care of him. This means feeding him, bathing him, petting him, and cleaning up any messes that he may make around the house. That way you will not be separated with the cat anymore.
