A local butcher whose meat and personality I didn't much like used to sell one pound blocks of frozen pet food, aka odd bits. I used to buy 10 pounds or so at a time from him, and nothing else. He always eyed my robust, rosy cheeked toddler with a wink and nod, and I'm sure he believed that that was what I fed the child.
Our sheepdog adored the stuff, which I mixed with kibble. But it stank to high heaven when being cooked up. If we were entertaining, I had to cook it early in the day in order for the barf-inducing scent to dissipate.
