Pet Food and Nutrition

Dr. Jean Hofve has more than 30 years of veterinary experience, and is a respected authority on holistic pet health and nutrition.  Her books, articles, and videos on pet food and nutrition have appeared around the world. She has been an official advisor to AAFCO, the organization that sets standards for pet food for almost 25 years. She has long been a voice for animals and against the powerful pet food lobby.

The Environmental Cost of Pets

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 ...

Grain-Free Dog (and Cat) Food, Taurine, and Heart Disease

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 ...

Cat Feeding Myths

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 ...

MOXXOR Omega-3s

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 ...

Pet Food: Processed to Death?

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 ...

Coconut Oil and Pets

Updated 5/17/20. Questions about coconut oil keep coming up, so I thought I'd explain in why I recommend not giving it to their cats and dogs. Humans have lived with coconut palms for millennia. Primates, including early humans, ate, and still eat, coconuts. Coconut is a natural food for us. The carnivore's natural diet is high in both protein and animal fat. Wild animals But there are only three essential fatty acids (EFA) that cats must obtain from their diet: linoleic acid (LA), alpha linolenic acid (ALA) and arachidonic acid (AA). ...

Pet Food Contaminants

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 ...

FDA Finds Toxic Sludge Going Into Animal Food

Many thanks to our good friend Mollie Morrissette for her excellent reporting on this issue. This is one more reason for why it is so important to have consumer representatives at AAFCO meetings--we provide a layer of protection (and a warning to these guys that we are watching!) when feed suppliers want to use harmful or non-edible feed materials. A similar ingredient ("Fat product, feed grade") was discussed at the last two meetings, and despite opposition from industry, was finally banned. Company warned to stop using revolting feed additives: Industrial grease, ...

Yucca

Photo credit: Jean Hofve Updated 6/6/20 There have been a few myths about the desert plant Yucca schidigera floating around the internet. In particular, some are suggesting that yucca is not safe as a daily supplement, even though it's present in many pet foods. So it's time to set the record straight! Yucca is an extremely versatile and useful plant, but in large doses it is seriously irritating to the entire GI tract. There's a lot of it growing wild around my Colorado home, and it's definitely not ...
