Well skaros i dont know....why should someone do that? Hitting an innocent creature...Anywayz the good thing is that you are sorry for what you did not some retards who feel proud of acting this way.This cat won't be alright for sure.Not only for the physical damage you caused to it but for the psychological damage too.This cat will never trust people.It will live its life in streets and probably will die without knowing that someone actually cares for it.The next time you'll face a similar situation please act like a mature man.And if your friends try to do what you didi please prevent them.
Now something a wise man said.
People who don't love animals don't love people
