Consumers are using artificial Intelligence (AI) in obvious places: diet recommendations, symptom checkers, product comparisons, and “best food” lists. These tools can organize information quickly and summarize options in a way that feels helpful and authoritative. None of this is inherently negative. None of this is inherently negative. These tools are fast and can make research quick and easy. But they also reinforce the idea that nutrition can be precisely modeled, optimized, and controlled based on available data. Where Does AI Get Its Information? AI does not generate knowledge independently. ...
Pets can be environmentally expensive. U.S. dogs and cats consume roughly a third of America’s animal-derived energy. Some analyses have blamed pet food for as much as 25–30% of the environmental impacts from animal production, including land use, water use, fossil fuels, fertilizers, and agricultural chemicals. That sounds alarming—but most estimates are based on theoretical models, not direct measurement. The results depend on how emissions are measured and allocated, and what assumptions the authors rely on. The most frequently cited analyses are also the most unrealistic. Pet food primarily uses ...
Updated 5/1/26. For years, conversations about weight issues and feline diabetes have centered on carbohydrates. This is not wrong; cats are obligate carnivores that are poorly equipped to manage large glucose loads. High‑starch diets (kibble, some canned diets, and even many raw diets that are too high in carbs) absolutely stress the pancreas and disrupt insulin metabolism. This alone can cause weight gain, insulin resistance, and an increased risk of type 2 diabetes. But it turns out that carbs are not the whole story. There is another factor that receives ...
Data suggest that diet is largely irrelevant in terms of extending longevity... On the other hand, there is plenty of research showing that the more prey-like the diet, the better for the cat. Certainly dry cat food has no place in the diet if longevity is the goal.
The story of copper toxicity from commercial pet food is really a "series of unfortunate events." You might be interested to see what goes on behind the scenes and how the pet food industry--how it's completely profit motivated and fundamentally uninterested in the health of our pets.

FINAL UPDATE 12/27/22 The FDA has closed its investigation into this matter, saying there is "insufficient evidence" to establish a causal link between diet and DCM in dogs. They will not be providing any further updates. NOTE: We now know that, as suspected all along, the purported link between grain-free pet foods and heart disease was entirely speculative. I can say with confidence that grain-free foods DO NOT cause heart disease in dogs or cats. There was and is no scientific evidence to support FDA's original theory, much less its naming ...
I admit, it really irks me when companies who know nothing about feline nutrition give bad advice to their customers. This is the case with Assisi Animal Health, which manufactures a device called the Assisi Loop. Now, the product is a good one and I've heard great reports about it. But they should stick to what they know! Here are a few of the things they got wrong in a recent article published by Business Insider. "Your first look at a bag of cat food should ensure that it has the American ...
Updated 11/13/25 With 80 zillion products on store shelves, you've probably gotten the message about Omega-3 fatty acids. But did you know that they're just as important for pets as for people? The anti-inflammatory effects of Omega-3s EPA (eicosapentanoic acid) and DHA (docosahexanoic acid) have been thoroughly researched, and are abundantly proven to be beneficial for dogs and cats. (If you'd like more background info, please click here for a more general article on Omega-3s.) I've been a big fan of Omega-3s for many years. In fact, I even served ...
The fish used in pet food may contain all kinds of toxins and drug residues, including persistent organic pollutants that actually stop the body from eliminating it and other toxins. Another common toxin, domoic acid, may be an unrecognized factor in chronic kidney disease.
Many thanks to Susan Thixton at TruthAboutPetFood.com for letting us reprint her excellent article here, which applies 100% to cat food as well as dog food. The multiple rounds of heat processing that pet food undergoes causes many deleterious changes that can harm our pets. And it's worse than most people even imagine. How many times are Ingredients cooked in Kibble Pet Foods? Do you know the processing involved in the manufacturing of kibble pet food? How many times are the ingredients cooked? The answer might surprise you. Pet food ...
Updated 4/29/26 Questions about coconut oil keep coming up, so I want to explain why I don't recommend giving it to cats. Cats Need the Right Fats The carnivore's natural diet is high in both protein and animal fat. There are only three essential fatty acids that cats must obtain from their diet: linoleic acid (LA), alpha linolenic acid (ALA) and arachidonic acid (AA). Adult cats can benefit from many other fats and oils, particularly EPA and DHA (which kittens require), but they aren't necessary for survival. Coconut oil is ...
Updated 3/23/18 As part of my duties as an AAFCO advisor and member of several Working Groups, I attend numerous webinars and teleconferences. In one group, the discussion centered around the use of 4D meats and other rotten junk in pet food, and the consensus was that as long as these things are rendered (heat-processed) to kill pathogens, they're perfectly fine for pet food. Well, that just isn't true. So I put together the following document to show that there are MANY potential toxic principles in pet food that need ...
