Cat food vs dog food - Ft

If you are a pet lover like us, you probably have both dogs and cats in your home, and with the high cost of food, especially during the pandemic, many people are starting to wonder what the differences are between dog and cat food and if they could both eat the same thing. If this is the case in your home and you would like to know if you can cut costs by combining foods, keep reading while we look at the ingredients of each type to see how they differ and how they are the same so you can make an informed decision.


Overview of Cat Food

What Is Cat Food?

There are two basic types of cat food, wet and dry. Manufacturers will cook the ingredients right in the can when preparing wet cat food, sealing in moisture and flavor. Dry food is like a biscuit or cookie mixed with ingredients and baked to hard, crunchy kibble. Both will provide your cat with a complete and balanced meal.

Cats are strictly carnivorous, so they require food high in animal protein. Unlike humans, they do not require any fruits, vegetables, or other plant matter in their diet. Animal proteins provide the cat with an important amino acid, taurine, which their bodies cannot create.

Which type of Cat Food Should I Choose?

When choosing a type of food for your cat, we recommend dry kibble over wet food. The crunching of dry kibble scrapes away tartar and plaque, helping to slow the progression of dental disease in your pet. Dental disease is a major issue for cats, and some experts suggest that more than 50% of cats have some form of dental disease by the age of four.

Wet food can be a great choice if your cat is constipated or dehydrated. Cats usually prefer wet food because it usually contains pieces of real meat, so it’s a great way to get a stubborn cat eating again or to give your cat medication. However, it doesn’t scrape away any plaque. In fact, the wet food can stick to the teeth, accelerating tooth decay.

  • A complete meal for carnivores
  • Wet food can accelerate tooth decay


Overview of Dog Food

What is Dog Food

Dog food is similar to cat food in many ways. Like cat food, dog food comes in both wet and dry varieties. The wet food has ingredients cooked in the can, and dry food has ingredients mixed with a cookie base. It can even look very similar, which is likely why many people wonder if you can mix and match the two types of food.

Dogs are omnivores, and unlike cats, they require fruits and vegetables in their diet along with animal proteins. Their bodies can create taurine, so they don’t require their food to include it.

  • A complete meal for omnivores
  • Doesn’t require taurine
  • Dogs require a more diverse diet.


What If My Cat Eats Dog Food?

If your cat ate some dog food while you weren’t looking, it would be fine. However, dog food does not contain the right nutrients that a cat needs to stay healthy. The biggest thing dog food is deficient in is taurine, essential for developing the kidneys, heart, and eyesight. The balance of other vitamins and minerals will be off as well. Since the cat does not possess the digestive tract to digest plant matter, eating dog food that contains these ingredients can upset your cat’s stomach.

Dogs are omnivores that can eat a wide range of foods, and if it were to eat cat food when you weren’t looking, it would be fine. Dogs are much less picky about what they eat, but just like when a cat eats dog food, the vitamins and minerals it contains will not be in the correct amounts to produce a healthy dog. Cat food is also quite rich compared to dog food, especially wet food, which can cause your dog to have an upset stomach and possibly diarrhea after consuming it

Its high-calorie content means you only need to feed half as much food to your pet, but you will need to follow portioning guidelines carefully, or it can quickly cause weight gain.divider-paw


While a dog or a cat may be able to enjoy a single serving of the other’s food on occasion, making it a regular part of their diet can lead to discomfort and even health problems. Dogs and cats have different diets that require nutrients in specific amounts, so it’s best to stick to the food that’s intended for them so your pet can be healthy and strong with a few health problems as possible.
