Can Cats Eat Peanuts? Everything You Need To Know

As a cat owner, one of the most important responsibilities is ensuring that your feline friend eats a balanced diet. While cats are known for their picky eating habits, it’s essential to provide them with a variety of foods to meet their nutritional needs. As a result, many cat owners may wonder whether it’s safe to feed their furry companion peanuts. I’ll explore the question, “Can cats eat peanuts?” and provide you with all the information you need to know about feeding your cat this popular snack.

Can Cats Eat Peanuts?

Cats can eat peanuts, but not in large quantities. There are some concerns about the fat content of peanuts, which is why you should limit how much your cat eats them.

Are cats allergic to peanuts?

Yes, cats can be allergic to peanuts! It’s important to note that peanuts are not actually nuts. They’re beans.

Peanuts are a common allergen in cats, and they can cause anaphylaxis or an allergic reaction that can lead to death if not treated immediately.

Symptoms of peanut allergy include:

  • Hives and itching
  • Runny eyes and nose
  • Trouble breathing

If you think your cat might be allergic to peanuts, talk to your vet about how best to treat it.

About Peanuts

Peanuts are actually legumes, not nuts. They grow in the ground and look like white beans when unripe, but when they’re fried or roasted, they turn brown and crunchy. They’re also known as groundnuts or earthnuts.


You may have heard that peanuts are bad for cats because they contain xylene (which can cause cancer) and other carcinogens, but this isn’t true! The trouble with xylene is that it’s found in many different foods—including coffee—so it’s difficult to pinpoint exactly where it comes from in any food product. The amount of xylene that cats consume from eating peanuts is actually very small compared to what they would get from other sources (such as coffee).

Health Benefits Of Peanuts

Peanuts are a great snack for cats. They contain lots of healthy fats and are even good for your cat’s brain. Here’s some more info on the health benefits of peanuts for cats!

  • Peanut is very nutritious for your cat. It contains healthy fats that are good for their skin and coat, which can help prevent hairballs, too!
  • Peanuts also contain vitamins E and B6, magnesium, and niacin. These vitamins are essential in helping to keep your cat’s skin and coat healthy.
  • They’re also a great source of protein! This is especially important if you’re feeding your cat an all-natural diet without any supplementation from other sources (like commercial pet food).

Disadvantages Of Peanuts

  • Peanuts contain an ingredient called arachidonic acid that can cause anemia in cats.

How To Feed Peanuts To Cats

If you want to feed your cat peanuts as a treat, there are a few things to keep in mind to ensure their safety and well-being.

  1. Consult with your veterinarian: Before feeding your cat any human food, it is important to consult with your veterinarian to ensure that your cat does not have any underlying medical conditions that could make certain foods harmful. Your vet can also advise you on the appropriate serving size for your cat.
  2. Choose unsalted peanuts: Salted peanuts contain a high amount of sodium, which can be harmful to cats and lead to health problems such as high blood pressure and kidney disease. Therefore, it is vital to choose unsalted peanuts for your cat.
  3. Avoid flavored peanuts: Flavored peanuts, such as honey-roasted or spicy peanuts, often contain additives and preservatives that can be harmful to cats. Stick to plain, unsalted peanuts.
  4. Serve peanuts in moderation: While peanuts are not toxic to cats, they are not a necessary part of their diet either. Peanuts are high in fat and calories, which can lead to weight gain and other health problems if your cat consumes too many. Therefore, serve peanuts as an occasional treat in moderation.
  5. Prepare peanuts appropriately: Cats may have difficulty chewing large pieces of peanuts, so it is best to crush or chop them into smaller pieces before serving them to your cat. This will also help prevent choking or digestive issues.
  6. Observe your cat’s reaction: Before feeding your cat peanuts for the first time, give them a small amount and observe their reaction. Some cats may have an allergic reaction to peanuts, which can cause symptoms such as itching, vomiting, or diarrhea. If your cat shows any signs of discomfort or illness, stop feeding them peanuts immediately and contact your veterinarian.


How many peanuts can a cat eat?

A cat can eat a small handful of peanuts per day (1-2); it’s important to avoid giving them too many nuts, as they’re high in fat.
If you give your cat peanuts, ensure they’re raw and unsalted.


All peanuts are, in fact, legumes. And like most legumes, peanuts are generally safe for your cat to consume in moderate amounts. This isn’t a rule, but keep in mind that your cat may have a negative reaction to peanuts if he is allergic to them.
