You know what's the biggest difference between that cat and a human? A human has the ability to defend himself, that cat is helpless, it's in pain and scared to death and can't do absolutely anything about it.
Just because he is not a human doesn't mean he doesn't feel pain and fear. He shouldn't have to take this just because some kid think it's fun.
With the history of his posts in this thread, the word "Troll" comes to mind, If one doesn't care about animals, why post in a thread about animal abuse?
Just my .02 Cents
