Clean Pet Food Revolution was a fun, engaging, and revealing read. I've long been excited about the transition away from animal products to clean foods. However, I never thought long and seriously about how pet food factors in. The authors deftly and wholly convinced me that we must consider pet food. Pet food accounts for roughly 25% of meat consumption in the United States. Animal agriculture could not stay financially solvent without the income stream of turning diseased carcasses and offal into pet food. Pet food is gross, ruining our world, and harming other animals in the process.The authors are unafraid to attack the naturalism fallacy (the more natural something is, the inherently better). They also note that the argument fails on its face. Obligate carnivory is more scientific miscategorization than a reflection of diets -- carnivores can eat plant-based foods and achieve their nutritional needs. Furthermore, ultimately all beings require nutrients, and nutrients are molecules. The providence of nutrients/molecules doesn't matter according to our best science. There's no reason that we can't have cat food that's plant/microbial-fermentation based and exceeds their nutritional requirements.Taurine is often used to counter arguments for non-meat cat food ("Taurine is required for cats, but only naturally occurs in meat"). But this argument fails as the book highlights. taurine is often chemically synthesized and added to meat-based cat food because the natural taurine is degraded during sanitization. So most cat food already isn't meeting nutritional demands de facto. And there's more evidence, as the book highlights, that both default dog and cat food are suboptimal nutritionally.In sum, I recommend this book to any pet owner or anyone else interested in the clean food transition. I'm looking forward to nutritionally-complete, plant-based food for cats. And I hope that pet food regulators such as the AAFCO will prioritize assessing and validating the ingredients. Our world needs these foods.
