Don't take this the wrong way: Your cat is not impressed by your yoga skills.
That's not to say your headstand is unimpressive. We who lack the core strength and balance to execute and hold that yoga pose (not to mention, most others) are downright wowed by your skill. We can barely touch our toes without groaning in pain. Kudos to you for being so fit.
But don't think for a second that your cat gives one iota of a darn about all of that. Look at him: He steps right in front of the camera, then pretty much goes to sleep. It's like getting served a steaming hot plate of kibble-flavored humble pie.
Cats -- they're just jerks.
