Can Dogs Eat Cat Food?

Dogs can technically eat cat food for a short period or in an emergency, but it’s not recommended as a regular diet. Cat food typically contains higher levels of protein and fat which are not suitable for a dog’s nutritional needs and can lead to obesity or other health issues over time. Regular consumption of cat food by dogs should be avoided to maintain their optimal health.

Risks Associated with Feeding Cat Foods to a Dog for a Long Time

Nutritional Imbalance

Cat food lacks the appropriate balance of nutrients for dogs, missing essential ingredients dogs need and containing others, like protein and fat, in excess. Over time, this can lead to deficiencies or excesses that may cause serious health issues in dogs, such as muscle wasting or pancreatitis.


Since cat food is richer in fats and proteins, dogs fed cat food regularly may consume more calories than necessary, leading to weight gain and obesity. This can increase the risk of joint problems, diabetes, and heart disease.

Gastrointestinal Issues

Dogs are not accustomed to the high protein and fat content in cat food, which can cause digestive upset, including diarrhea and vomiting. Chronic digestive problems can lead to dehydration and nutrient malabsorption.

Liver and Kidney Strain

The higher protein content in cat food can put additional strain on a dog’s liver and kidneys as these organs work to process the excess proteins and byproducts, potentially leading to organ damage or failure over prolonged periods.

Behavioral Issues

A dog that learns to eat cat food may start seeking it out, leading to problematic behaviors like food stealing, guarding, and aggression. This can disrupt the harmony in multi-pet households and complicate feeding routines.

What to do if your Dog accidentally eats Cat Food?

If your dog accidentally eats cat food, monitor them for any signs of gastrointestinal upset, such as vomiting or diarrhea. In most cases, a small amount once off will not harm them, and they should be fine. Ensure they have plenty of water to drink and resume their normal dog-appropriate diet. If you notice any adverse reactions or if your dog has consumed a large quantity of cat food, contact your veterinarian for advice.

Nutritional Profile: Cats vs. Dogs

Cats require diets with higher overall protein (about 30-35% dry matter basis), fat (about 20%), and specific nutrients like taurine. Dogs need slightly less protein (about 18-25% dry matter basis), fat (about 10-15%), and more fiber (about 2.5-4.5%). Vitamins and minerals are essential for both but in different quantities, such as more vitamins A and C for cats, as they cannot synthesize them.

When Cat Food is Good for Dogs?

For some canines, particularly those contending with illness-induced weight loss or diminished appetite, the enhanced palatability and calorie density of cat food may make it a beneficial temporary substitute over standard dog food. Its higher nutrient levels can also serve as a more balanced option compared to certain homemade diets, specifically in instances where maintaining weight is crucial.

Moreover, cat kibble could be a more nutritionally balanced treat or incentive during training sessions when contrasted with typical human snacks, like peanut butter or cheese, which often deliver a high amount of calories from a single nutrient category. However, this should be considered only under veterinary guidance to ensure overall health and nutritional needs are met.

Tips to Keep Your Dog Away From Cat Food

  • Training: Train your dog to obey commands like “leave it” or “back away,” using positive reinforcement techniques. This helps control their impulses and ensures they stay away from cat food during unsupervised moments.
  • Separate Feeding Areas: Keep the cat’s feeding area separate and inaccessible to your dog. You can feed your cat on higher surfaces, like countertops or cat trees, or in a room with a pet gate that only the cat can enter.
  • Scheduled Feeding Times: Avoid free-feeding your cat, which leaves food out all day. Instead, establish specific feeding times for both pets, removing the cat’s food bowl after mealtime to prevent grazing and temptation.
  • Secure Storage: Store cat food in secure containers or locations your dog cannot access. This prevents the dog from being tempted by the smell or sight of cat food between feeding times.
  • Distract and Reward: Provide your dog with engaging toys or their own treats during the cat’s feeding times to distract them. Rewarding them for ignoring the cat food reinforces good behavior.
  • Physical Barriers: Install baby gates or pet gates that have a small opening or cat door at the bottom, allowing your cat access but keeping your dog out of the designated feeding area.
