I've had pets that have sat near me, breathing in my sidestream smoke, whenever I had gear or joints on the go -- and they always toddled off again and lay down on their beds, when they'd had as much as they wanted.
My first cat, Chico (R.I.P.) was absolutely fascinated by foil. Miss the bin with a bit of crumpled-up foil, and he would spend hours just batting it around the floor with a paw. If you left a tooter on the table, he would come over and sniff it, and maybe even try to steal it. Mever mind Puss in Boots, said a mate of mine withnessing this behaviour for the first time, He's more like Puss Having a boot! Chico also used to climb up my shelves, dig in my box of candles, pick up a tealight by the wick in his teeth, then go and stash it in of his little catty hiding-places.
I lost him far too young, in a freak accident. A few years later, my current cat, Spook, managed to get himself into the same situation that Chico did before; but this time, we knew exactly how to save him, we acted in time and he made a complete recovery. It was as though Chico had reached out from beyond the grave, to save Spook's life.
