Welp. My cat just got glared at really hard.
He's not too sure why, but he thinks it may be the vomit in my shoe I had to clean up this morning. That or knocking something off is what usually gets him glared at.
You're kidding, right? Cats don't respond in that way. It won't occur to the cat that the glare is because of anything he might have done wrong. He'll just notice you're in a bad mood.
It's the same with punishments. Dogs are pack animals. Packs need tight teamwork to hunt, etc, so packs do punishment and dogs understand punishment. Swat a dog with a newspaper, and the dog immediately thinks, "I MUST HAVE DONE SOMETHING WRONG!" Cats are pride animals, which is a completely different headspace. Prides share space socially and often share food, but prides don't require tight teamwork in hunting and don't use punishment to train group members to that teamwork. Cats don't understand punishment. Swat a cat with a newspaper and the cat thinks socially instead of in terms of teamwork. It goes, "Geez, this guy is being an asshole."
And of course, the responses are completely different. A dog will try to alter its behavior to please you, exactly like a team member who's been called on not contributing correctly. A cat will avoid you until you're in a better mood or stop behaving like an asshole, exactly like someone sharing social space but who has no idea that their behavior (any behavior at all other than social interaction itself) is meaningful to you.
So.... don't bother glaring at cats. It doesn't help.
