low carb diet catDry 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.

It can be difficult to find the right low-carb cat food for your furry friend. 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.

    Buyers Guide

    Cats are obligate carnivores, and this is the main reason that 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, though, is protein, which should be of a significantly higher percentage in your cat’s food. When buying a low-carb food for your feline friend, there are several factors to take into consideration.

    Grain-free

    Most low-carb cat foods on the market are advertised as grain-free, but this does not necessarily mean they are carbohydrate free. Grains that are often put into commercial cat foods as fillers include wheat, soya, and oats, and these are all considered carbohydrates. Any food using these fillers is likely to have a high carbohydrate-to-protein ratio. However, other forms of carbohydrates are regularly included in commercial cat food, and they come in two different varieties: simple carbohydrates and complex carbohydrates. Carbohydrates in their simple form are easily digested by the body as simple sugars, including sucrose and fructose. Complex carbohydrates include vegetables like potatoes and beans.

    So, while grain-free foods are free of carbohydrates like wheat and soy, they can still contain a surprisingly high amount of carbohydrates from included 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 to have a lower concentration of carbs, a maximum of 10%.

    Why low-carb?

    There are many arguments for and against carbohydrates in cat food, and the debate still rages on. Still, a cat’s natural carnivorous instincts mean they should at least get a high protein-to-carbohydrate ration 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 health, build muscle and organs, and help them grow healthy fur.

    Other than protein being your cat’s main dietary need, another reason to feed them a low-carb diet is diabetes. Carbohydrate-rich foods will cause sugar spikes in your diabetic cat, and this can be highly 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.

    Dry vs. Wet Foods

    This is another aspect in which the debate still rages on, but there are several significant benefits of feeding your cat wet low-carb foods over dry. It is difficult to make dry kibble without the use of some form of carbohydrates, due to the starch present 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, then dry kibble should be avoided.

    Wet food is made with high moisture content and thus doesn’t require the binding of ingredients. The added moisture from wet foods to your cat’s diet is highly beneficial, as your cat gets a large percentage of their hydration from their food.
