Can Cats Eat Salt?

When it comes to human nutrition there are perhaps no greater villains than fat and salt. However, did you know that table salt is an essential nutrient, required by all living creatures to survive?

If salt is so important, can cats eat salt? And, if so, how much salt is too much your feline companion?

In this article we’ll cover the following:

  • Cats and Salt, What You Need to Know
  • Are Some Salts Poisonous to Cats?
  • Benefits and Drawbacks to Your Cat Eating Salt

Cats and Salt, What You Need to Know

When nutritionists talk about “salt” in the diet, they are specifically referring to sodium chloride. For both humans and cats, saltiness is one of the basic taste sensations, and sodium chloride is an essential nutrient.

The daily recommended allowance of sodium for a nine-pound cat is about 42 mg. That is not very much when you consider this is about the sodium content in 6 Pringles potato chips or a slice and a half of pepperoni.

Unrefined or natural salts can contain other minerals that meet dietary needs. These salts often have desirable flavors associated with the impurities they contain and have become a quite popular culinary item.

Given salt’s popularity, it’s no surprise the cat in the following video would be interested in some salt:

Are Some Salts Poisonous to Cats?

Table salt is just one of thousands of compounds that are “salts” from a chemistry perspective. Other ionic compounds, such as calcium chloride, used as ice-melt on roads, also can have a salty taste.

However, these other “salts” make cats ill or even kill them. Some, such as sodium hydroxide, or lye, can even cause chemical burns if it comes into contact with skin.

While it’s not possible to go into an in-depth discussion of all the other salts here, it is important to note that you need to keep chemicals of any type away from your cat. Their life could depend on it.

Benefits and Drawbacks to Your Cat Eating Salt

In humans, there is quite a bit of evidence linking increased sodium consumption to hypertension as well as cardiac and renal diseases. However, in cats, a 2-year study failed to show that increases in dietary salt intake were harmful to a cat’s renal function or raised their blood pressure.

This doesn’t mean that a high salt diet is good for cats. It just indicates that their bodies are more tolerant of sodium than ours.

Cats have kidneys that are much more efficient at concentrating and excreting salt in their urine. A study from many years ago showed that cats given only salt water not only survived, but actually thrived.

The verdict is still out on whether high-salt diets are detrimental to cats who already have kidney or renal disease. If your cat does have renal disease, follow your vet’s advice which will probably include a recommendation that your cat not eat a high-sodium diet.

As long as your cat is eating a high-quality, well-balanced cat food, there are few benefits to your cat eating salt. Perhaps the only time you would add salt is if you are making your cat’s food from scratch.

Homemade cat foods are becoming increasingly popular. This is particularly true when a cat has specific health problems that can be addressed through a specialized diet.

Since salt is an essential nutrient, sufficient salt must be added to the other ingredients to make a balanced diet. Additionally, a little added salt can make a food much more more palatable, as can be seen by the popularity of potato chips with people and cats like O’Malley in the following video:

Can Cats Eat Salt?

Remarkably, cats can eat table salt with few negative health effects. However, there are many other chemical compounds containing sodium that are also “salts” that must be kept away from your cat because they are very poisonous.

Generally, you don’t need to add table salt to your cats or kitten’s diet as they are healthiest when fed a well-balanced diet made specifically for them. The only exception would be if you are making homemade cat food and the recipe calls for table salt.
