Tonight the humans had corn on the cob for dinner. And they thoughtfully left the used cobs in a bag on the counter. It would have been nice if they actually left the UN-eaten cobs out for me too, but an Estrela can cope with sub-standard food.
But here's the confusing thing... when I got a corn cob out for a little post-dinner snack, the humans actually yelled at me and took it away.
They hung the bag full of husks (ok, even I won't stoop so low as to eat those) and cobs up on a cabinet doorknob. I will have to treat this as a personal challenge.
