Yes, I read about that.
Not just an idiot; vicious and violent, ugly and downright nasty.
According to the Guardian, apparently there is a video (a video? Who on Earth would want to - would choose to - make a video of such a thing?) of Zouma dropping, kicking, and slapping the cat. Not content with that, apparently, he then threw a pair of shoes at the unfortunate animal.
While West Ham (entirely to their credit) swiftly - and strongly - condemned the player's actions, expressed appalled horror, and apologised, the player's own apology, which included the following remarks, "I would like to assure everyone that our two cats are perfectly fine and healthy. They are loved and cherished by our entire family, and this behaviour was an isolated incident that will not happen again," struck me as less then entirely credible in the circumstances.
