Can Cats Eat Salt – A Surprising Answer?

We all know that cats are big fans of food. There are plenty of food choices available that cater to their nutritional requirements. Occasionally, if your cat doesn’t enjoy their food, you might consider adding some salt for flavor. However, is it safe for cats to consume salt in large quantities? Can cats tolerate salt?

Cats should avoid consuming salt that is not already included in their regular diet. Consuming more than 42 milligrams of salt per day can have negative consequences for cats. Excessive salt intake can lead to vomiting, dehydration, and an imbalance of electrolytes in cats.

Although salt is commonly found in cat food, it is important to use the right amount to prevent any negative effects on your cat. We will provide useful details about the role of salt in a cat’s diet and the appropriate quantity they should consume regularly.

How Much Salt Is Safe For Cats

Cats can safely consume around 21 – 43 milligrams of salt. However, if they consume more than that, it can lead to issues such as vomiting and extreme dehydration.

If you don’t add extra salt to your cat’s food, it’s crucial to ensure that the salt content in their dry food remains below 0.2%. This helps your cat grow properly and maintain regular bodily functions.

Here’s a comparison of how much salt is in different cat foods, including both regular ones and special prescription ones.

Brand Food Type Sodium Percentage
Hills Prescription Wet 0.23 – 0.27
Blue Vet Wet 0.3
Blue Buffalo Dry >0.2%
Royal Canin Dry >0.2%

Is Salt Harmful To Cats

Large amounts of salt can be dangerous for cats. It can actually be toxic and have negative effects on your cat’s overall well-being.

If cats consume excessive amounts of salt, they can develop kidney problems and may even have tremors. In more serious situations, cats that regularly consume too much salt may experience swelling in the brain.

All of these things can cause physical problems for your cat, like your cat having trouble balancing or using the litter box correctly.

There are various types of salt, and it can be difficult to determine where your cat might have consumed too much salt. Here are some everyday things and ingredients found in homes that have high levels of salt:

  • Seawater
  • Rock salt
  • Salt shakers
  • Salt lamps

If you have cats and a fish tank at home, it’s crucial to keep an eye on your cats when they’re near the tank. Cats might casually approach the tank and drink the water, but they might not be aware that the water could contain a lot of salt.

To keep your cat safe, make sure to store away any seasonings and even salt lamps that could be accidentally spilled and licked up by your cat.

Rock salt is a risky way for pets to get salt poisoning. It can get trapped in a cat’s paws, and since cats are naturally clean animals, they will attempt to lick it.

If your cat lives in a snowy area and walks through the snow, they may experience this problem. In such a situation, it is important to provide immediate care to your cat, treat the condition, rehydrate them, and restore their sodium levels to normal.

Do Cats Like Salt

Yes, cats enjoy salt. But just because they like it doesn’t mean they should have it whenever they want. Salt can be included in a cat’s food in small amounts, but it needs to be measured carefully.

Cats already get some salt from their food, and adding more can greatly affect how much they eat. According to the chart above, most cat food is required to have sodium levels below 0.2%. However, certain wet foods may exceed that percentage.

Salt is a simple taste that cats like. They also enjoy sweet, bitter, and sour things. So, salt is not really any different. Your cat will naturally like it, but you need to be cautious and not give in to their requests.

Instead of adding salt to your cat’s food, try changing the food itself. This ensures that your cat still gets the right amount of sodium without changing the food.

Does Salt Make Cats Sick

Indeed, cats can become ill from consuming salt. While the salt that is typically present in their food is unlikely to cause any harm, adding extra salt on top or mixing it in can lead to serious issues.

What Happens If A Cat Has Too Much Salt

If a cat consumes an excessive amount of salt, it can have negative consequences. These may include the following:


If your cat consumes too much salt, one obvious indication is vomiting. The food it has recently eaten will be regurgitated. Salt has a natural tendency to induce vomiting when ingested in excessive quantities, so it is not surprising that it would have the same effect on your cat.

If your cat is experiencing this, it’s important to ensure they drink enough water. Then, you can try reducing the amount of food they eat for the rest of the day.

Maybe try giving them snacks instead of a full meal so you can slowly introduce salt into their daily diet.

Once your cat has recovered, you can gradually reintroduce them to their regular food or think about switching to a gentler option that won’t upset their stomach!


If cats experience diarrhea, it can be quite uncomfortable for them. They will need to go to the bathroom often. If you observe this happening suddenly after giving your cat excessive sodium, that is probably the reason.


If a cat consumes excessive amounts of salt, they will quickly become tired and lose their enthusiasm. A cat that was once playful and full of energy will become very lazy and uninterested in their surroundings. This change in behavior can be observed immediately, whether it’s their lack of interest in toys or treats.

When a cat is feeling lazy, it is usually weak as well. During this time, the cat may also have an imbalance of electrolytes. Other symptoms that may be seen in a lazy cat include:

  • Weight loss
  • Fever
  • Aggression
  • Increased urination

Lack Of Appetite

After consuming excessive sodium, cats may experience a decrease in their desire to eat, along with symptoms like laziness and loose stools. However, the effects of sodium on cats differ slightly from those on humans.

If a cat loses its appetite, it can have negative effects on other aspects of its daily life. This can lead to various issues such as:

  • Seizures
  • Dehydration
  • Problems with coordinating movements and maintaining balance

All of these are equally worrying. If a cat experiences seizures because of consuming too much salt, it is most likely salt poisoning. This occurs when the cat consumes an excessive amount of salt and needs immediate medical attention.

Dehydration is a common issue for cats. While salt usually increases hunger and decreases thirst in humans, it has a different effect on cats. After eating, you may notice your cat panting.

After that, it’s pretty normal to notice your cat going back to the water bowl often. Make sure to pay attention to how they drink because they might gulp too much, which can make them feel sick and vomit. All of this can result in serious dehydration.

Cats are famous for their excellent coordination, so if they lose their balance, it’s a cause for worry. If a cat eats salty food, it may display symptoms of imbalance or confusion.

How Do You Fix Salt Poisoning In Cats

Even if you keep a close eye on your cat, accidents can still occur. If you think your cat has consumed too much salt, there are a few steps you can take to assist in resolving the issue.

The first thing you should do is take your cat to the vet right away. Vets can give your cat IV fluids to remove the extra salt from their body. This is the best way to restore the right amount of sodium in your cat’s body.

A veterinarian can also run tests on your cat and keep an eye on other important information. This includes checking the balance of electrolytes, treating any additional dehydration, and monitoring your cat’s brain activity.
