There is a lovely tranquility about this video. It’s something unique to cats, that delicate elegance. You wouldn’t get 2 dogs practising a gentle, conservative martial art. No way. Sniffing each other’s arses? Yep. Biting each others faces? No problem. Beautiful, calm movements…no way.

No wonder they say people with the feline species live longer. They are a tranquil influence on even the most fretted minds. These guys are in combat, allegedly, and still they manage to transfix and reduce stress. And they’re so uniform as well. Anyone could be forgiven for thinking a mirror was involved.
