If you're trying to say it's not his fault he kicked Wilfred I suggest rereading that section of the post. He might have done it accidentally, but he shouldn't really have been running through the house anyways even if he wanted to clean his shoes asap. The thirty seconds he would've saved won't change much and it's a tripping risk (or a cat kicking one). Also asking what is wanted of him is if you kick a cat hard enough to fling said cat into a wall it's common decency to stop and make sure it's okay. That can severely injure the poor cat, but he decided his shoes were more important than a pet he himself had personally agreed to take care of. I'd say it's 100% his own fault. The cat didn't hit a running person, so much as he hit it.
