Dry cat foods commonly have hidden carbohydrates in them, including grains, that are used as fillers to bulk the food up. Because cats are carnivores, they only require a small amount of carbs in their diet, and too much can quickly cause obesity and diabetes.
A cat’s diet will benefit greatly from a low-carb and high-protein intake, as this matches their natural diet. Some cats require low-carb food if they have diabetes or other health issues, and in those cases, it is actually essential.
Finding the right low-carb cat food for your furry friend can be difficult. We’ve done all the hard work for you, however, and put together this list of in-depth reviews to help you make the right choice to suit your unique needs.

The 10 Best Low-Carb Cat Foods
1. Smalls Human-Grade Fresh Cat Food Subscription – Best Overall
When it comes to a balanced feline diet, you can’t go wrong with Smalls Fresh Cow. We found it to be the best overall low-carb cat food because of its balanced nutrition and tasty recipes. About 50% of the product’s calories come from protein and about 47% come from fat, while only 3.2% of the calories come from carbs. The Fresh Cow recipe contains ground beef, beef liver, and beef heart, with some supplemental ingredients to add vitamins and minerals. Smalls operates on a subscription-based service that sends your cat food straight to your door on the timetable of your choosing.
The fresh meat model does have some drawbacks. Unlike kibble-style or canned foods, Smalls Fresh Cow isn’t shelf-stable, so it requires freezer space to store and time spent thawing in the fridge. A freeze-dried or canned option might be a better choice if you are always running low on freezer space.
Overall, we think this is the best low-carb cat food available.
- Human-grade beef
- High protein, low filler food
- Comes in smooth and ground blends
- Requires freezer space to store

Several users report that their cats would not eat it, and the protein content is not ideal for kittens. These two small issues keep this food from the top position. For the money, though, we think this is the best low-carb cat food.

Buyers Guide: Selecting the Best Low Carb Cat Food
Cats are obligate carnivores, which is the main reason their carbohydrate intake should be kept to an absolute minimum. That said, some carbohydrates are beneficial to your cat’s diet, provided that they are the right kind, as they can provide an energy source for your cat. What your cat really needs to thrive is protein, which should be of a significantly higher percentage in your cat’s food. When buying low-carb food for your feline friend, there are several factors to take into consideration.
Most low-carb cat foods on the market are advertised as grain-free, but that does not necessarily mean they are carbohydrate-free. Grains that are often put into commercial cat foods as fillers include wheat, oats, corn, and rice, and they are all carbohydrates. Any food using these fillers is likely to have a high carbohydrate-to-protein ratio. Other forms of carbohydrates that are regularly included in commercial cat food are starches such as tapioca and potato.
So, while grain-free foods are free of carbohydrates like wheat and corn, they can still contain a surprisingly high amount of carbohydrates from fruits and vegetables.
When is cat food considered low-carb?
Considering that cats are carnivorous, an ideal ratio would be around at least 50-60% protein, 15-30% fat, and 5-15% carbohydrates. A low-carb food would ideally need a maximum of 10% carbohydrates.
There are many arguments for and against carbohydrates in cat food, and the debate still rages on. Still, cats are carnivores, which means they should at least get a high protein-to-carbohydrate ratio in their food. They are natural predators, and a high-protein diet is essential for them to live happy and healthy lives. Protein will help your cat’s gut, organs and bodily functions, and overall health.
Other than protein being your cat’s main dietary need, another reason to feed them a low-carb diet is diabetes. Carbohydrate-rich foods are the reason cats and humans are suffering from the disease. Carbohydrates cause blood sugar spikes, worsening the condition in a diabetic cat, which s can be dangerous. Overweight or obese cats will also greatly benefit from eating a low-carb diet, as it will reduce their sugar and grain intake significantly.
Ironically, many sick cats are on “special diets” due to diseases they suffer for not receiving the carnivorous diets they needed in the first place.
Dry vs. Wet Foods
This is another aspect in which the debate still rages, but there are several significant benefits of feeding your cat wet low-carb foods over dry. It is difficult to make dry kibble without using some form of carbohydrates due to the starch in carbs that will prevent the kibble from crumbling. This means that most dry foods on the market will have more than 10% carbohydrates. If your cat has no health issues, the occasional bowl of dry food will not hurt, but if they need to avoid carbs as much as possible, dry kibble should be avoided.
Wet food is made with high moisture content and thus doesn’t require ingredient binding. The added moisture from wet foods to your cat’s diet is highly beneficial since your cat gets a large percentage of their hydration from their food.
Regardless of whether you feed your cat dry or wet food, you need a bowl that is sure to keep the mess contained—you can do just that with the Hepper Nom Nom Bowl. This is designed with your cat’s comfort in mind. The whisker-friendly bowls are low and wide to prevent whisker fatigue, and the wide catch tray ensures that all food stays exactly where it should—inside the bowl. At Excited Cats, we’ve admired Hepper for many years and decided to take a controlling ownership interest so that we could benefit from the outstanding designs of this cool cat company!
