You need to take that poor cat to someone who will take proper care of it and NOT hit it....you scum bag.
And throwing it outside where it can be attacked by other animals, get into harmful chemicals, or get shot with bbs or any of the dangers of allowing cats to go outside is also terrible. And irresponsible.
Not only are they vulnerable to a litany of harmful and deadly things....they can also be a menace to wild life like birds, destroy neighbors gardens....ect.
You are a bad cat owner and clearly a drug user.
