They don't put the good stuff in cat food. It's all the stuff that I throw out when I'm cleaning fish I caught myself. For instance they put the heads, guts, hearts, esophagus, and from the tuna they put the dark red line that runs down the sides.

Dog food has chicken heads, feet, beaks, esophaguses and tracheas, lungs, kidneys, etc. in it. In fact the cheaper brands of dog food has "meat and bone meal" which is made from tankage which is like condemned cows and horses and god knows what else in it. When I used to work at the Vet School all the stuff that went out the back of Necropsy got sent to the rendering plant and turned into meat and bone meal.

I was thinking about these facts when I read the article. There is no doubt, raising meat (especially cattle) for consumption is a major impact on carbon footprint. But dogs and cats don't really expand the human footprint caused by raising animals for food so much as they extend the usefulness of the footprint already created. If they weren't making dog and cat food out of those by-products, much of it would likely simply be discarded.

In this study, I believe they simply counted up kilos of meat by-products required to feed Fido and assumed the same ratio of meat to hectares required to raise animals for human consumption.
