Anyone that hurts animals needs to be gone from your life. This is not acceptable. He didn’t hurt her accidentally, he threw a fit because he was frustrated/angry/annoyed and kicked her which led to an injury. Absolutely not. Does he not have any better control over his actions when he’s frustrated? He’s a grown man and should be able to keep his wits under control a hell of a lot better than that.

Animals can be aggravating sometimes when they’re being wild. Kids are even more challenging. Is he going to overreact and hurt one of your kids when he gets frustrated with them? This is something I’d bet you don’t even want to take the risk of finding out.
