A Twitter user posted a video of his cat and dog watching TV on the couch. While the dog blissfully stares at the TV, the cat studies the dog carefully and then launches its attack.

The dog immediately responds and knocks the cat off the couch, which makes you wonder why the cat bothered attacking the dog in the first place. Fortunately, the Twitter user reported that his dog and cat get along with each other so it’s all harmless fun (we hope).
