It's kind of like fluffing a pillow... only on a larger scale and way more adorable!
Wait, no, you've got it all wrong! I'm not jumping for joy in a figurative sense. In fact, I'm actually feeling a little down today... my kibble this morning was a bit stale, and it really threw me into a strange kind of funk! Rather, I'm literally jumping for Joy, because that's my human's name, and she requested that I jump. Which is totally fine, because a.) I like her so I like doing tricks for her and b.) she promised to compensate my leap with a milkbone.
Pssk, hovercats? Don't compare me to those faux-flying felines! Their maximum elevation is a paltry 100 meters! I can fly MILES HIGH without even winding myself! I think it's time that all the would-be aeronautical cats of the world just face the facts and admit that they don't even have a hope of being as aerodynamic and flyable as we bunnies are!
