I like this CORS much better.
At one point she would sniff our backpack straps, with over a decade of accumulated sweat and human residue and go absolutely mental, rolling around in them like it was catnip.
She's also just an extremely attentive cat so it might all just be a game to her.
That's why it's good catiquette to let the cat smell your finger before you pet it.
