Animal owners tend to live under the assumption that their animals don't actually understand them. You look at your hooligan, delinquent cat in the eyes as it's about to drop one of your favorite teacups onto the floor, and you say "no", and your cat looks at your like you're insane/insanely stupid and does it anyway. Maybe they really don't understand for the most part, but some animals...
Some animals are smarter than we give them credit for. It's not because they don't understand that they're not allowed to do it either. These tumblr posts clearly show that your pets understand exactly what they're doing. They do it because they're jerks. And they're jerks on purpose. And we love them anyway lol.
