Why Oats Are Not an Appropriate Food for Dogs and Cats

When it comes to feeding our pets, we want to provide them with the most species-appropriate diet possible. While many commercial pet food brands and homemade diet advocates promote oats as a nutritious and beneficial ingredient, the truth is that oats—and grains in general—are not well-suited for dogs and cats. Here’s why:

1. Dogs and Cats Are Carnivores by Design

Dogs are facultative carnivores, meaning their bodies are designed to thrive primarily on animal-based proteins and fats, though they can consume some plant matter in survival situations. Cats, on the other hand, are obligate carnivores, requiring a diet that consists almost entirely of animal-derived nutrients. Oats and other grains do not provide the essential amino acids, vitamins, and fatty acids that carnivores need to maintain optimal health.


2. Oats Contain Anti-Nutrients

Grains, including oats, contain anti-nutrients such as lectins, phytic acid, and enzyme inhibitors that can interfere with digestion and nutrient absorption. Phytic acid binds to essential minerals like zinc, calcium, and magnesium, preventing their absorption. This can lead to long-term deficiencies that impact bone health, immune function, and overall vitality in both dogs and cats.


3. Carbohydrate Overload and Blood Sugar Spikes

Oats are high in carbohydrates, which can cause rapid spikes in blood sugar levels. This is particularly concerning for pets prone to obesity, diabetes, or metabolic disorders. Unlike humans, dogs and cats have limited amylase production, an enzyme necessary for breaking down carbohydrates. This means that feeding them carb-heavy foods like oats places unnecessary stress on their digestive systems and can contribute to long-term health issues.


4. Potential for Inflammation and Gut Issues

Many pets experience food sensitivities or intolerances to grains, which can manifest as skin issues, chronic ear infections, digestive upset, or joint inflammation. Oats contain gluten-like proteins that may trigger inflammatory responses in sensitive pets. Additionally, feeding grains can contribute to an imbalance in the gut microbiome, leading to poor digestion and an increased risk of leaky gut syndrome.


5. Nutritional Deficiencies in a Grain-Based Diet

Oats do not provide the bioavailable nutrients that dogs and cats require for optimal health. While some argue that oats contain fiber, vitamins, and minerals, these nutrients are better obtained from raw, species-appropriate sources like organ meats, bone broth, and fermented vegetables. Feeding grains can displace more nutritionally dense foods, leading to imbalances over time.


A Species-Appropriate Alternative

Instead of oats, consider offering your pet whole, fresh foods that align with their biological needs. High-quality raw or gently cooked meat, organ meats, and small amounts of low-glycemic vegetables (for dogs) provide the essential nutrients they need without the drawbacks of grains. For fiber and digestive health, options like raw pumpkin seeds, green tripe, or fermented vegetables are far superior to oats.


Final Thoughts

While oats may seem like a wholesome, comforting food for humans, they do not align with the natural dietary needs of dogs and cats. Prioritizing a diet rich in biologically appropriate animal proteins and healthy fats will ensure your pet thrives, rather than simply survives. If you’re unsure about what diet is best for your pet, consider booking a personalized nutrition consultation to create a meal plan tailored to their specific needs.
