Can Cats Eat Dog Food?

Cats are certainly capable of eating wet and dry dog food (as evidenced by my own moggy who will happily try to dislocate his jaw in an effort to eat giant-sized dog kibble!), but from a nutritional perspective, cats really shouldnt eat dog food.

Is It Safe for Cats To Eat Dog Food?

Dogs have evolved and become domesticated over tens of millions of years alongside us humans. This has led to altered genetic coding and a shift from pure carnivorous fare to an omnivorous diet.

Cats, on the other hand, have really only started to become domesticated in relatively recent times, thus maintaining their original genetic codes and dietary preferences. In essence, cats are obligate carnivores. This means that, unlike dogs, they have a very specific and essential requirement for nutrients obtained from animal sources such as meat.

Every animal on earth has specific dietary requirements with a key number of essential nutrients that must be obtained from food. Some, like us humans, actually require far less to be supplied in our diet than either dogs or cats.

In other words, cats can eat dog food, but it wont supply the nutrition they require.

The Uniqueness of Cats

Cats have a uniquely developed gastrointestinal tract.

This starts in the mouth with a total of 30 adult teeth (dogs have 42), all of which are designed for cutting and tearing. They are also unable to move their jaws in a sideways motion, which limits their ability to grind. That grinding motion is essential for eating plants, but its not necessary for a meat-eating carnivore.

A cats stomach is designed for accommodating many small meals throughout the day.A single mouse contains approximately 30 kcals, which roughly accounts for 10-15% of an adult cat diet. This means that in the wild, feral cats need to eat up to 10 small meals per day.

Additionally, cats small intestines are highly adapted to digesting protein and fat rather than carbohydrates. Add to this a very acidic stomach pH for the breakdown of small bones and rapid transit time through the entire intestinal tract, and it soon becomes clear that cats are highly adapted hunters.

Feline Nutrition 101: Why Cats Need So Much Protein?

Kittens require about 60% more protein compared to adult dogs, whereas adult cats require roughly 44% more.

So Why Do They Need So Much Protein?

Cats require more protein per pound of bodyweight than dogs do.

Cats rely heavily on protein as their main source of glucose in the body. Glucose is the bodys primary fuel. It provides the energy for every function in the body from growth, to breathing to thinking to physical repair. Glucose is required at a cellular level to simply allow the body to function.

In cats, most of their energy is obtained from protein breakdown in the liver, but the liver has a fixed rate of activity to achieve this. Ultimately, if cats dont obtain sufficient protein in their diet to meet this energy requirement, they will start to break down their own body protein or muscle.

Protein is made up of chains of amino acids and a number of these are only found in meat.

Herbivores and omnivores have the ability to create these amino acids from other plant-based protein sources, but cats are unable to do this.

They rely so heavily on protein as a significant energy source in the body, that they have evolved not to waste this precious resource on converting amino acids that can readily be obtained from eating animal tissue. Consequently, all cat food must be formulated to contain sufficient levels of taurine and arginine in particular. Without enough of these amino acids supplied through food, cats are at risk of developing heart disease, eye disease, and neurological disease.

But cats dont only require essential amino acids to be supplied in their food. They also have a unique requirement for a specific omega-6 fat called arachidonic acid.

It is essential for cell membrane and function, as well as healthy skin. Dogs are able to manufacture this from alternative fatty acids in their diet, but as youve probably guessed by now, cats are unable to do this.

Finally, cats have extremely specific vitamin requirements. Unlike dogs, cats are unable to manufacture Vitamin A, Vitamin D, and Vitamin B3 from other sources. Oily fish is a great source of vitamins A and D, whilst liver and chicken are great sources of vitamin B3.

Can Cats Eat Carbohydrates?

While cats are obligate carnivores and can convert protein and fat into glucose, they can also utilize carbohydrates as an energy source.

There is a lot of myth and misunderstanding about cats and carbohydrates. Unlike the essential nutrients listed above, cats do not have a specific requirement for carbohydrates in their diet. Nonetheless, carbohydrates are a great source of energy in the form of glucose, as well as dietary fibre.

Cats do not have the enzyme glucokinase, which is the main enzyme used by the mammalian body to breakdown carbohydrate and extract glucose. Instead, they have an enzyme called hexokinase and this performs the same function in cats, thereby allowing them to utilise highly digestible carbohydrates.

We already know that cats obtain most of their energy needs from the breakdown of protein, so even though they dont need carbohydrates, they can use them as an alternative energy source if required. More importantly, cats benefit from the dietary fibre contained in highly digestible carbohydrates to enhance their gut health.

Final Thoughts

Pet parents often ask if can cats and dogs eat the same food, the answer is that despite the common misperception that cats will do just fine eating canned, soft or even dry dog food and even though they may actually seem to enjoy eating dog food (as evidenced by my own cat!), it should be quite clear by now that cats are very unique and highly specialised predators.

They have extremely specific dietary requirements and even though they can eat and digest nutrients from plant sources, they should never become vegetarian. Ultimately, however much they may behave like their canine counterparts, cats are not small dogs.

Frequently Asked Questions

Can a cat get sick from eating dog food?

If your cat, like mine, is determined to sneak into the kitchen and raid the dog food bowl at every available opportunity, then I would suggest feeding both species separately or at the very least removing your dogs food after mealtime is over, to limit the temptation. In the short-term, there is minimal risk of cats becoming sick if they occasionally snack on dog food.

However, providing dog food regularly as a source of nutrition to cats will make them very ill over time. Dog food simply doesnt contain the essential nutrients that cats need to survive, let alone thrive. Without essential amino acids such as taurine and arginine cats can become blind and potentially even die.

Why is my cat eating the dog food?

The reason why some cats are tempted by dog food remains a mystery to us humans! There are some simple explanations, though:

Is your cat hungry?

Check that youre providing the recommended amount of total daily food to your cat by consulting the feeding guidelines on pack and always, always, always weigh out the food for each meal

Is it due to mouth feel?

Cats rely a lot on their senses when it comes to food. They have an extremely limited gag reflex, which makes vomiting extremely difficult (think of any time youve watched a cat try to bring up a hairball). In turn, this makes them very choosy about what they put in their mouths. They rely a lot not just on how food smells or tastes, but also on how it feels in their mouths. Perhaps they dont like the texture or form of their own cat food, but something about dog food is more appealing to their senses? Try experimenting with different types of food such as freeze-dried, wet, dry, semi-dry, etc to see if your cat prefers one type over another.

Is it behavioural?

Does your cat view food as essential to survival? Did they suffer as a kitten by going without food for a period of time? If this is the case, then your cat may well be subconsciously driven to eat anything that comes within paw-reach.

Is there a food for both dogs and cats?

Due to the myriad of essential nutrients that cats absolutely require from their food, which isnt present in most dog foods, the short answer to this question is no. However, there are times when both dogs and cats have an increased requirement for nutrients, far above recommended minimal levels such as when recovering from a serious illness. During these times, there are foods available on veterinary recommendation that are specifically formulated with increased nutrient levels to suit both dogs and cats to aid their convalescence.

Can cats eat dog food in an emergency?

In case of an emergency, cats are capable of eating dog food. But from a nutritional perspective, cats really shouldnt eat dog food.

Purina Moist and Meaty Dog Food Review (Semi-Moist)

The Purina Moist and Meaty product line includes the 6 semi-moist dog foods listed below.

Each recipe includes its AAFCO nutrient profile: Growth (puppy), Maintenance (adult), All Life Stages, Supplemental or Unspecified.

Recipe and Label Analysis

Purina Moist and Meaty Burger with Cheddar Cheese Flavor was selected to represent the other products in the line for detailed recipe and nutrient analysis.

Ingredients Analysis

The first ingredient in this dog food includes beef by-products, slaughterhouse waste. This is whats left of slaughtered cattle after all the prime cuts have been removed.

With the exception of hair, horns, teeth and hooves, this stuff can include heads, ovaries or developing fetuses.¹

And raw meat contains up to 73% water. So, after cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.

After processing, this item would probably account for a smaller part of the total content of the finished product.

The quality of this ingredient can vary, depending on the caliber of the raw materials obtained by the manufacturer.

The second ingredient is soy flour, a high-protein by-product of soybean processing.

Although soy flour contains about 51% protein, this ingredient would be expected to have a lower biological value than meat.

And less costly plant-based products like this can notably boost the total protein reported on the label a factor that must be considered when judging the actual meat content of this dog food.

The next ingredient lists soy grits, soybeans which have been toasted and broken into small pieces. Although high in protein, compared to meat, soy grits are an inferior source of amino acids.

The fourth ingredient is high fructose corn syrup (or HFCS). HFCS is a corn-based sugar mixture commonly used to make soft drinks, cookies and candy. Sugar is an empty nutrient just as unhealthy for dogs as it is for humans.

The fifth item is water, which adds nothing but moisture to this food. Water is a routine finding in most canned dog foods.

The sixth ingredient is wheat flour, a highly-refined product of wheat milling. Like corn, wheat is an inexpensive and controversial cereal grain of only modest nutritional value to a dog.

For this reason, we do not consider wheat a preferred component in any dog food.

The seventh ingredient is corn syrup. Corn syrup is a glucose-rich, high-calorie item of questionable nutritional value to a dog.

Next, this recipe includes beef. Although its a quality item, raw beef contains up to 73% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.

After processing, this item would probably account for a smaller part of the total content of the finished product.

From here, the list goes on to include a number of other items.

But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this product.

With 7 notable exceptions

First, soybean oil is red flagged here only due to its rumored (yet unlikely) link to canine food allergies.

However, since soybean oil is high in omega-6 fatty acids and contains no omega-3s, its considered less nutritious than flaxseed oil or a named animal fat.

In addition, were always disappointed to find artificial coloring in any pet food. Thats because coloring is used to make the product more appealing to humans not your dog. After all, do you really think your dog cares what color his food is?

Next, we find no mention of probiotics, friendly bacteria applied to the surface of the food after processing to help with digestion.

In addition, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Chelated minerals are usually associated with higher quality dog foods.

We also note that this food includes menadione, a controversial form of vitamin K linked to liver toxicity, allergies and the abnormal break-down of red blood cells.

Since vitamin K isnt required by AAFCO in either of its dog food nutrient profiles, we question the use of this substance in any canine formulation.

This product also uses sodium selenite, a controversial form of the mineral selenium. Sodium selenite appears to be nutritionally inferior to the more natural source of selenium found in selenium yeast.

And lastly, this food contains ethoxyquin, a controversial preservative linked to the accumulation of hemoglobin pigment in the liver and elevated hepatic enzymes in the blood.

Nutrient Analysis

Based on its ingredients alone, Purina Moist and Meaty looks like a below-average product.

The dashboard displays a dry matter protein reading of 27%, a fat level of 10% and estimated carbohydrates of about 55%.

As a group, the brand features an average protein content of 27% and a mean fat level of 11%. Together, these figures suggest a carbohydrate content of 54% for the overall product line.

And a fat-to-protein ratio of about 39%.

Which means this Purina product line contains

Near-average protein. Below-average fat. And above-average carbs when compared to a typical dog food.

When you consider the protein-boosting effect of all the soy products, this looks like the profile of a semi-moist dog food containing a moderate amount of meat.
