Pet Food Sharing: Can Cats Eat Dog Food? (& Vice Versa?)

When it comes to mealtime, it's not uncommon for cats and dogs to get curious about what lingers in their furry sibling's bowl. You're not alone if your dog ate cat food once or twice, or if your cat ate dog food or treats — the occasional food swap isn't a big deal. But, if it becomes part of their daily routine, it's time to correct this behavior.

Let's discover why your pets shouldn't share the same kibble or eat each other's foods, what happened inside your pet's body last time your dog ate cat food (and vice versa) and how we can discourage meal swapping once and for all.

Problems With Pets Sharing Foods

It may seem easy to simply fill a big bowl with one food and let all your pets munch and crunch as they desire throughout the day, but there are several reasons why this isn't recommended. For starters, you have no idea how much food each pet is consuming. Are they overeating? Not eating enough?

Let's say you do feed each pet individually, but you have a sneaky pup who likes to eat the cat's dinner for dessert. Your dog may be ingesting too many calories for the day, which could lead to obesity and other related health issues. Also, when a dog eats cat food, they're not getting the proper ratio of protein, fiber and other nutrients needed to maintain their healthy lifestyle. This can lead to gastrointestinal problems, strain on the liver and kidneys, pancreatitis, or a number of other issues. The same can be true if your cat is sneaking your dog's food. Not to mention, cats require a few nutrients, like taurine and arachidonic acid (a type of at) that are not required by dogs, and therefore, not always monitored in dog food. In the long run, a cat eating dog food may experience nutrient deficiencies whereas a dog eating cat food is more likely to experience problems associated with excess energy or nutrients.

Is one of your pets eating therapeutic food? Therapeutic foods are specially made for dogs or cats experiencing specific conditions that can be managed with nutrients at levels (higher or lower) than are found in "regular" foods. Extra care should be taken to make sure only the pet that needs this food eats it. If you do find that the food was eaten by another pet in the household, call your veterinarian to learn about possible reactions or concerns, as well as next steps to keep your pet healthy.

Feed Your Pet Foods Formulated for Their Species

Because of dogs' and cats' unique biology each species needs a different balance of nutrients. The best dog and cat food brands consider your pet's biology before formulating the pet food. They will also take things such as lifestage, health conditions, certain pet food allergies, breed size (for dogs), activity level, and a number of other factors into consideration before crafting a food that is right for a certain type of dog or cat.

This matters because all of those factors contribute to the overall health of your dog or cat. Think about it, you wouldn't put the wrong type of gasoline into your car, would you? So, while you shouldn't be too concerned if a kibble or two gets swiped, you should discourage them from sharing each other's food when possible.
