First up we have Xena showing how the arboreal kitten can navigate complex branch structures without falling off. In fact she doesn't even have to look where she's going. She feels her way along the branch using paws, claws and a cleverly aligned tail for extra balance control.
Next up we have Kai demonstrating what can go wrong.
And remember, kittens, don't try this at home. Kai is a fully trained stunt kitten and is used to hanging precariously from great heights. It's what he does best. Students of balance will note how he's hanging on by a combination of the back paws clawing at one horizontal while his front paws grasp the one above. His posture is wrong, his torso twisted and his tail is having to curve forward to compensate.
If any kittens are wondering how Kai got into that mess in the first place, here is Kai demonstrating The Wobbly Kitten - a high banister manoeuvre without a net. Any second that back end could go and he'd be swinging from the banisters with his back paws around his ears.
But Kai recovers, regains his balance and then ... makes the mistake of looking down.
Another warning for aspiring arboreal kittens, keep your eyes on the branches around you because sometimes when you look down...
Your legs go weak. And it's all too much.
