Low-Carb Feline Diet

Cat Diets:  Things to Keep in Mind

Cats are Carnivores

Cats are obligate carnivores and are metabolically designed to consume diets with the following general composition:

  • Animal (not plant)-based protein (>50% calories),
  • Moderate fat (~20-45% calories),
  • Very low carbohydrate (1-2% calories),
  • Water-rich (~70%).

Keep this in mind when choosing food for cats but also understand that pet food ingredients are profit margin-driven. Animal protein is more expensive than plant protein, fat, and carbohydrate sources (grains, potatoes, and vegetables). Therefore, there are not many diets on the market that mimic the above composition - except for the favorable water content found in all canned, not dry, foods.

Hydration is Important

Cats have a low thirst drive and are designed to get their water needs met by their prey or food bowl. Canned food (vs dry kibble) promotes urinary tract health and optimal systemic hydration which is especially critical for cats with kidney insufficiency.

“Grain-free” Does Not Necessarily Mean “Low-Carb”.

Potatoes and peas are often used in “grain-free” products which *may* result in a high carbohydrate diet. This is why it is important to consider the composition (% calories from protein/fat/carbohydrate) and not just the ingredient list. The ingredient list does not tell you how much potato, rice, vegetable matter etc., is in a product. If the diet is low in carbohydrates, there can’t be much of those ingredients in the product. Note that “gravy” foods tend to be high in carbohydrates.

Check the Nutritional Information

100% of a diet’s calories come from protein, fat, and carbohydrate. Therefore: % protein calories + % fat calories + % carbohydrate calories = 100% This means that if, for example, a diet is appropriately low in carbohydrates, the diet will be higher in protein, fat, or both. It is like a three-way teeter totter - if one fraction goes up or down, one, or both, of the other two must increase or decrease accordingly. Companies vary greatly in their willingness to provide basic ‘typical nutrient analysis’ data. Many companies provided data promptly or they post the data on their website (gold stars to them) but it was necessary to call and email a number of companies many times before receiving any information.

Three companies (BLUE BUFFALO, BY NATURE, & STELLA & CHEWY’S) refuse to provide ‘typical nutrient analysis’ data, stating that it is “proprietary” information. By taking this stance, they are suggesting that consumers do not have the right to know the nutrient composition of the diets they are purchasing for their pets. It is up to the consumer to decide whether to support these companies with their purchasing dollars or to choose another company’s products. Note that the information requested for inclusion on this list is not excessive and is freely stated on many pet food company websites. It is basic nutritional information that all pet food manufacturers should make readily available.

How much should I feed?

The average 10 pound cat requires about 200 kcal (calories) per day. Cats should always be fed according to their ideal weight: if they are chubby, feed less for the amount we’d like them to weigh. Keep in mind that dry foods are much more calorie dense than canned foods. On average it takes about 2-3 cans of food to equal the calories in about ½ cup of most dry foods.
