What should I do? I want to report my cousin to an animal rescue.
Why do you want to report your cousin?
I hate him for what he's done. He's cruelly hurting those poor animals
It is hard to report somebody especially if they are family, but you need to do what you need to do to protect animals. They need your protection and they cannot protect themselves.
What do you know? You're not a real person.
Making an anonymous report about your cousin is okay to do. It's good to step in when someone is mistreating innocent animals.
