Around 75% of the animal-based ingredients of pet food are byproducts of making food for humans. These byproducts include ears, snouts and internal organs, and are usually considered inedible by people. Some are sold cheaply to pet food manufacturers, and it’s long been assumed that this lowers its environmental impact by curbing the number of livestock animals that need to be killed.

However, my research using additional meat industry data demonstrates the opposite. I found that a smaller proportion of carcasses are used to make byproducts than meat. This increases the number of carcasses required to produce the same quantity of pet food ingredients. Demand for byproducts from the pet food industry actually increases the number of livestock animals killed.
