Can dogs eat cat food? If your dog seems a little too curious about what's in your cat's bowl, then it's important to know if it's safe for your dog to give your feline's food a little taste test. 

One of the age-old questions that frequently puzzles dog owners is whether it's acceptable for dogs to indulge in cat food.

To answer - is cat food bad for dogs? - you'll need to gain an understanding of the distinct dietary needs of dogs and cats and their more varied diet requirements.

Yes, dogs love cat food, but it should never be a part of a healthy adult dog’s diet. A dog eats cat food because it tastes good (especially wet cat food), but that doesn't mean it's beneficial for a dog's health. Even human food is better for dogs than dry cat food.

So, before you let your dog sneak a taste from the cat's dish, let's shed light on the intriguing matter of dogs eating cat food.

This article will help you decide whether feeding cat food to your dog is truly a good choice or if you should stick to dog food.

Can Dogs Eat Cat Food?

We often get asked, "Why can't I just give my dog and cat the same food?" Most dogs like cat food, right? 

Typically, we would say no, your dog shouldn't eat cat food, but it's a slightly more complicated answer than you might think. 

The true answer is that it depends on the food. Common commercial pet foods, like kibble, are very different between species. In this case, dogs shouldn't eat cat food.

These diets are often too high in fat and calories and are not properly portioned for dogs, leading to digestive issues, pancreatitis, and unwanted weight gain when fed regularly. Wet cat food is often formulated similarly. 

Raw dog and cat foods may be a little different. Yes, there are some dog and cat-specific formulas, but many whole-prey raw diets are suitable for both dogs and cats.

Brands like Big Country Raw and Carnivora offer single protein raw formulas are meet the needs of any carnivore. 

Dietary Differences Between Dogs and Cats

There are many differences between the dietary needs of dogs and cats, but there are also similarities. It starts with how and what they are designed to eat.

Kitties are generally more adept at self-regulating their food, with only a few bites here and there of cat food. They prefer to eat smaller, more frequent meals throughout the day. In contrast, dogs eat dog food usually twice a day.

Carnivore vs. Omnivore

Felines are obligatory carnivores, which means their diet must primarily consist of animal-based proteins. When you introduce cat food, you must make sure it meets the high meat-based protein needs of the feline.

In the wild, cats hunt and consume prey animals, and their bodies have evolved to efficiently process and derive essential nutrients from animal tissues. The cat tree of evolution hasn't changed much with your house kitty.

On the other hand, your dog is an omnivore, capable of digesting both animal and plant-based foods. Their digestive systems have adapted to process a wider variety of nutrients, including carbohydrates.

Protein Requirements

Due to their carnivorous nature, cats have a higher dietary protein requirement compared to dogs. Protein provides vital amino acids that felines cannot produce on their own, making it essential for their overall health and well-being.

Doggos also require protein but typically at lower levels compared to felines, or they will experience weight gain.

Taurine in Cat Food

Taurine is an amino acid that is crucial for felines but not required in significant amounts for dogs. Kitties cannot synthesize sufficient taurine in their bodies and must obtain it from their diet. A taurine deficiency can lead to severe health issues in cats.

Only cat food ingredients focus on taurine as a necessity in your cat's food bowl. This is why when cats eat dog food, they can become dangerously ill.

Vitamin A in Dog Food

Unlike dogs, cats cannot convert beta-carotene (a precursor of vitamin A) into the active form of the vitamin. Therefore, cats need to consume preformed vitamin A, which is found only in animal tissues.

Canines, on the other hand, can convert beta-carotene into vitamin A, making plant-based sources a potential source for them in dog foods.

Arachidonic Acid in Cat Kibble

Another essential nutrient for cats is arachidonic acid, which is an omega-6 fatty acid found primarily in animal tissues. Kitties cannot efficiently produce this acid.

Doggos can synthesize arachidonic acid from linoleic acid, an omega-6 fatty acid found in various plant oils.

Carbohydrate Tolerance

Canines have a higher tolerance for carbohydrates in their diet compared to cats. While dogs can derive energy from carbohydrates, felines are less efficient at utilizing them and primarily rely on proteins and fats for energy.

Cutting back the carbs does not always promote weight loss. Healthy adult dogs require a balance.
