Can Cat Food Make Dogs Sick

We’ve all heard the phrase “curiosity killed the cat,” but what about our four-legged friends on the other side of the pet spectrum?

Dogs, known for their hearty appetites and adventurous spirits, are no strangers to exploring culinary options outside their designated kibble. One of their most tempting targets is Cat food.

It’s a scene in countless households: a dog sneaks into the cat’s domain and indulges in a forbidden feast of feline delicacies.

But as adorable and seemingly harmless as this scenario may appear, there’s a lingering question that responsible pet owners must ask: Can cat food make dogs sick?

Understand the Difference Between Cat and Dog Food

Understand the Difference Between Cat and Dog Food

It is very important to understand the difference between pet food before discussing the dog’s sickness if they eat cat food. The nutritional requirements of cats differ from those of dogs, and they impact each other.

1. Nutritional Needs:

  • Protein Requirements: Cats love meat, meaning a large portion of their diet is protein. Their bodies’ increased protein and other amino acid needs to be addressed. Another side is that dogs can thrive, and their diet includes animal and plant-based sources.
  • Taurine: Taurine is an essential amino acid for cats to maintain good heart and visual functions. Because dogs can partially generate taurine in their bodies, dog food normally contains less.
  • Vitamin A: Compared to dogs, cats are less effective at converting some substances, such as beta-carotene, into active vitamin A. As a result, although dog food may rely more on sources of beta-carotene, cat food frequently contains preformed vitamin A.

2. Protein Sources:

  • Meat Content: Typically, cat food has more animal-based protein sources like meat and fish. In contrast, the protein sources in dog food formulas may vary between animal and plant sources.
  • Fatty Acid Profiles: Arachidonic acid, largely present in animal tissues, is one of the fatty acids cats need in a particular balance. Different fatty acid compositions may be present in dog food to meet the needs of dogs.

3. Nutrient Ratios:

  • Calcium and Phosphorus: Compared to dogs, cats need a different proportion of calcium to phosphorus in their diet. Health problems may result from these minerals’ imbalances.
  • Calorie Content: Due to cats’ increased energy needs, cat food frequently contains more calories per serving than dog food, which is manufactured to have a more balanced calorie profile.

Why Do Dogs Eat Cat Food?

Can Cat Food Make Dogs Sick

It’s a scene that many pet owners are familiar with—a dog stealthily sneaking into the territory of their feline housemates to indulge in a forbidden feast of cat food. But what drives dogs to consume cat food, and why is it such an irresistible temptation for them? Let’s explore some common reasons behind this behavior:

Palatability and Taste:

Cat food often boasts a strong aroma and flavors particularly appealing to dogs. Many cats prefer meat-based diets, and their food reflects this. The high protein content and fat levels in cat food can make it more enticing to dogs than their kibble.

Scent Attraction:

Dogs have an acute sense of smell and can detect the enticing scent of cat food from a considerable distance. This heightened olfactory sensitivity makes it difficult for them to resist investigating the source of that alluring aroma.


Competition for food can be a motivating factor in multi-pet households where both cats and dogs reside. Dogs might see cat food as a delicacy and want to ensure they don’t miss out on what their feline companions enjoy.

Dietary Instincts:

Dogs have evolved from carnivorous ancestors, and their dietary instincts still lean toward consuming meat. Cat food is high in animal-based protein and aligns more closely with these ancestral instincts.

Variety and Novelty:

Dogs, like humans, can get bored with a monotonous diet. Cat food may offer a change in flavor and texture, providing a novel eating experience that dogs find intriguing.

Social Learning:

Dogs are observant and often learn by watching the behavior of other animals in the household. If they see cats enjoying their meals, dogs might be tempted to try it themselves.

Potential Risks of Dogs Eating Cat Food

Potential Risks of Dogs Eating Cat Food

While the occasional nibble of cat food is unlikely to harm your dog, consistent or excessive consumption can lead to various health risks and complications. Let’s explore these potential dangers in detail:

1. Digestive Upsets:

  • Gastrointestinal Distress: Cat food is formulated differently from dog food, often containing higher fat content and different protein sources. These variations can lead to digestive upsets in dogs, including diarrhea, vomiting, and stomach discomfort.
  • Pancreatitis: Dogs are more likely to get pancreatitis because of the high-fat content of cat chow. Pancreatic inflammation is a defining feature of this excruciating illness that may be fatal.

2. Nutritional Imbalances:

  • Protein Overload: Cat food typically contains a higher percentage of protein, which, if consumed consistently, can put undue strain on a dog’s kidneys and liver. This excess protein can lead to kidney issues over time.
  • Lack of Essential Nutrients: Although cat food is nutritionally balanced for cats, it is deficient in several essential elements for dogs. Dogs may experience health issues if they lack certain vitamins and minerals.

3. Allergies and Sensitivities:

  • Allergic Reactions: Ingredients like particular proteins or chemicals frequently found in cat food might cause allergies or sensitivities in dogs. This may lead to gastrointestinal troubles as well as skin and itching concerns.
  • Digestive Allergies: Dogs with sensitive stomachs or food allergies may respond negatively to the changes in ingredient compositions between cat and dog food.

4. Obesity and Weight Management:

  • Excess Calories: Cat food frequently has more calories than dog food. Dogs who regularly eat cat food are more likely to get overweight and develop health problems like diabetes and joint difficulties.
  • Difficulty in Weight Control: Managing a dog’s weight can be challenging if they are accustomed to the calorie-rich cat food. Weight management has become a crucial concern.
