Cats’ bodies are powerhouses. Their hearts pump at a rate of 170 beats per minute. They can jump, prowl, smash, bite, and claw. They’re some of the fastest animals, most skillful climbers, and apex predators around our households – but their kidneys are fragile. They say that a cat’s kidney is as thin as a piece of paper.
Unlike us, cats can’t afford to salt their meals and rely on their large kidneys to evacuate excess salt. Sodium is, of course, necessary in a cat’s daily diet, but to a different degree and in different proportions. The recommended daily doses of sodium per pound are much smaller than those for humans, for example.
Cats suffering from kidney malfunction have to take in even less sodium to protect their kidneys. Some health conditions also require a low sodium diet. Here, we bring you a complete review and guide for the best low sodium cat food you can order online.
Healthy Low Sodium Nutrition
To create a balanced and affordable diet, we first have to recommend mixing wet and dry food in your cat’s daily diet, especially if its condition is related to gastrointestinal problems. Always provide enough fresh water along with the meals.

3. Hill’s Science Diet Adult Indoor Cat Food Chicken
The final low sodium cat food on our list, the Hill’s Diet Indoor Formula is packed with good proteins with high absorbability and the formula is adapted to suit the needs of a regular house cat. The sodium level is low and is recommended as a precautionary measure.
Prevention is the best cure.
The food is packed with natural fibers that promote healthy microbes in cats’ intestines and support digestion. The kibble is small and soft so cats like to munch on it, reducing the chance of swallowing the kibble whole, which can lead to gastric irritations.
A balance of proteins, fats, and carbohydrates ensures a healthy energy boost throughout the day allowing a cat to feel satisfied until the next meal.
- Protein: 36.1%
- Fat: 16.1%
- Carbohydrate: 31.7%
- Sodium: 0.55%
- Taurine: 0.23%
- Calories: 319 Kcal/cup
Sodium content is problematic due to the complexity of its effects on a cat’s health. Some companies, therefore, resort to hiding or making it difficult to find the sodium content in their products.
For example, they may introduce sodium through neutral compounds that change structure once they go through the digestion process rather than flat out seasoning the kibble with salt.
As most of us are not veterinarians or pet nutritionists, it’s hard to track sodium placement in the cat’s body. One thing is for sure, all that sodium has to go through the kidneys. Though sodium is vital for the healthy functioning of cells, cats have to be extra careful.
Below is our breakdown of the best cat foods with low sodium.
