Can cats eat dog food?

Cats should not be fed dog food. While it is not harmful for cats to have an occasional bite of dog food, a consistent diet of dog food can lead to nutrient deficiencies and serious health issues in the long run.


In many homes with multiple pets, it’s not unusual for a curious cat to sneak a bite or two from the dog’s food bowl. This often raises a critical question among pet owners: is it safe for cats to eat dog food? This article aims to delve into this inquiry, taking into consideration the distinct dietary requirements of cats and the extent to which dog food fulfills these needs.

Understanding Cat’s Diet

Cats are defined as obligate carnivores. This implies that their diet must consist primarily of meat. They require specific nutrients such as taurine, arachidonic acid, and vitamin A, which are found in abundance in meat sources and not adequately present in plant-based food. These nutrients play crucial roles in numerous physiological functions in cats. Taurine, for instance, is essential for cardiovascular health, eyesight, and reproduction. Arachidonic acid, a type of fatty acid found in animal tissues, is vital for cats for skin health, blood clotting, and healing, whereas Vitamin A is critical for vision, growth, and immune function (Sturges, 2019).

Comparing Cat Food and Dog Food

Despite both cats and dogs being carnivorous and enjoying meat-based diets, there are significant differences in the nutrient composition of their respective foods. Cat food is specially formulated to include nutrients that cats cannot produce on their own or don’t get enough from other sources. These include taurine, arachidonic acid, and vitamin A. Dog food, conversely, is crafted to meet a dog’s nutritional needs, which differ from those of cats. Dog food typically contains less protein and fat compared to cat food. Moreover, dog food lacks the essential nutrients required by cats in the right quantities (Hamper, Bartges & Kirk, 2020).

Can Cats Eat Dog Food?

While it won’t harm a cat to occasionally nibble on a small amount of dog food, a sustained diet of dog food can lead to nutrient deficiencies and the ensuing health problems in cats. Dog food lacks the adequate amounts of taurine, arachidonic acid, and vitamin A that cats need. For instance, a deficiency in taurine can lead to a severe heart condition known as dilated cardiomyopathy and even blindness in cats. A lack of vitamin A can cause serious skin and coat problems and issues with vision. Moreover, the lower protein and fat content in dog food compared to cat food does not fulfill the energy requirements of cats, which could lead to malnutrition over time (Bellows, et al., 2020).

Potential Risks of Feeding Dog Food to Cats 

Consistently feeding dog food to cats can pose several health risks due to the insufficient nutrient content. Potential health issues include cardiovascular diseases resulting from taurine deficiency, skin and coat problems due to a lack of arachidonic acid, and vision problems from insufficient vitamin A. Furthermore, the lower levels of protein and fat in dog food may lead to weight loss and malnutrition in cats if fed regularly. Over time, these deficiencies can lead to severe and potentially life-threatening conditions (Hamper, Bartges & Kirk, 2020).

Expert Opinions

Most veterinarians and pet nutrition experts advise against feeding dog food to cats. They emphasize that cats have unique nutritional requirements that cannot be met by dog food (Bellows, et al., 2020). Therefore, cat owners should aim to provide their pets with a balanced diet specially formulated for felines. These diets are designed keeping in mind the high protein, fat, and essential nutrient requirements of cats.

Alternatives to Dog Food for Cats

If your cat shows an interest in dog food, consider providing cat-friendly alternatives to keep their diet varied and interesting. High-protein foods, wet foods, and foods with added taurine are all excellent choices for cats. You may also consider introducing different flavors and textures of cat food to satiate your cat’s curiosity for new food items.


In conclusion, although cats may show interest in dog food, it is not suitable for their unique dietary needs. Consistent feeding of dog food to cats can lead to serious health issues over time due to nutrient deficiencies. Therefore, it is essential to feed cats a balanced diet specifically designed for them and consult a veterinarian if there are any concerns about the cat’s nutrition.
