Can Cats Eat Walnuts? The Truth About Feeding Nuts to Your Feline

Cats should not eat walnuts. While they aren’t toxic, walnuts can be difficult for cats to digest and may lead to gastrointestinal issues. In some cases, moldy walnuts can contain toxins harmful to cats. It’s best to keep walnuts away from your feline to avoid any potential health risks. Stick to cat-safe treats instead.

Why Do Cats Like Walnuts?

You might be wondering—if walnuts aren’t good for cats, why do some cats seem so interested in them?

Well, cats are naturally curious creatures. They love to explore new smells, tastes, and textures. Walnuts, with their rich, oily scent, can be particularly intriguing to cats. They may not be interested in the taste of the walnut itself, but the scent can attract them.

Some cats also chew on walnuts out of boredom or even during teething. The hard texture of the walnut can feel good on their gums. But just because your cat is interested in walnuts doesn’t mean they should be eating them.

Can Cats Eat Walnuts Every Day?

No, cats should not eat walnuts every day. Walnuts are high in fats and oils, which are difficult for cats to digest and can lead to digestive issues like vomiting, diarrhea, and even pancreatitis if consumed regularly. 

Additionally, walnuts pose a choking hazard due to their size and texture. While one walnut might not cause immediate harm, feeding them daily increases the risk of health problems.

Are Cooked Walnuts Safe for Cats?

No, cooked walnuts are not safe for cats. While cooking can eliminate some toxins, it doesn’t address the primary concerns associated with walnuts.

1. High Fat Content:
Cooked walnuts remain high in fats, making them difficult for cats to digest. This can cause digestive issues, which may result in vomiting and diarrhea.

2. Risk of Pancreatitis:
Feeding your cat cooked walnuts can increase the risk of pancreatitis, a serious inflammation of the pancreas. Symptoms may include abdominal pain and lethargy.

3. Choking Hazard:
The size and hard texture of walnuts, even when cooked, pose a choking risk for cats, especially smaller breeds.

4. No Nutritional Benefits:
Cooked walnuts do not provide any nutritional value for cats. It’s essential to focus on foods that meet their dietary needs.

Can Cats Eat Walnuts from the Ground?

You’re out in your backyard, enjoying some fresh air with your cat, and you notice walnuts scattered on the ground, fallen from a nearby tree. Your cat, curious as always, starts sniffing around the walnuts.

So, can cats eat walnuts that have fallen from a tree?

While it might seem harmless, walnuts that have fallen to the ground can pose even more risks than fresh walnuts. For one, mold can grow on fallen walnuts, and certain types of mold produce mycotoxins that are highly toxic to cats.

If your cat ingests a walnut contaminated with mold, they could experience symptoms like tremors, seizures, and even death in severe cases.

So, whether the walnut is fresh or fallen, it’s best to keep them out of your cat’s reach.

What About Other Nuts? Can Cats Eat Them?

While nuts are popular as snacks for humans due to their high nutritional value, they don’t offer the same benefits for cats. Most nuts are unsuitable for feline consumption and can lead to various health problems. Here’s an expanded look at some common nuts and their potential impact on your cat’s health:

1. Almonds

Almonds might seem harmless since they are frequently part of a healthy diet for humans, but for cats, it’s a different story. In small amounts, almonds are not considered toxic; however, they can cause digestive issues, especially if eaten in large quantities. 

Some cats may experience vomiting or diarrhea after consuming almonds because their digestive systems aren’t equipped to process the fats and oils in nuts efficiently. Additionally, almonds are a potential choking hazard, especially for smaller cats. 

While a single almond may not seem dangerous, it’s best to avoid giving them to your cat at all. Flavored or salted almonds are particularly dangerous due to added seasonings that can be harmful to cats.

2. Pecans

Pecans are another nut high in fats and oils, which can spell trouble for your cat’s digestive system. While pecans aren’t technically toxic to cats, they’re not suitable for their diet. 

Cats who consume pecans may experience gastrointestinal upset, including vomiting, diarrhea, and abdominal pain. The high fat content also increases the risk of pancreatitis, a serious condition that requires immediate veterinary care. 

Beyond digestive issues, pecans are large and hard, posing a choking risk, particularly for small or young cats. In short, feeding pecans to your cat is not advisable.

3. Macadamia Nuts

One of the more dangerous nuts for pets is the macadamia nut.Macadamia nuts are poisonous to both cats and dogs. While research has mainly focused on the toxicity in dogs, there’s evidence that cats could suffer similar ill effects. 

If a cat consumes macadamia nuts, they might exhibit symptoms like weakness, tremors, vomiting, hyperthermia (increased body temperature), and lethargy. 

The exact toxin in macadamia nuts that causes these reactions remains unknown, but even a small amount can lead to severe health problems. Macadamia nuts are best avoided entirely and should be kept out of reach of your cat.

4. Peanuts

Peanuts are one of the more common nuts people feed their pets, but there are some important considerations. Peanuts are not toxic to cats, but they should still be given with caution. The main issue with peanuts is their high-fat content, which can be hard for cats to digest. 

This could lead to stomach upset or more serious conditions like pancreatitis if consumed regularly. If you do decide to give your cat a peanut, make sure it’s unsalted and unflavored, as salt, seasonings, and added oils can harm your cat’s health. 

Peanut butter, while sometimes used as a treat for dogs, isn’t recommended for cats. Many peanut butters contain added sugar, salt, or even xylitol, an artificial sweetener that is highly toxic to pets.

5. Cashews

Cashews are another type of nut that, while not toxic, isn’t recommended for cats. Like other nuts, cashews are high in fats and oils, which can disrupt your cat’s digestive system. 

Cats who eat cashews may experience vomiting, diarrhea, or even pancreatitis, especially if cashews are consumed in larger quantities. Moreover, cashews can be a choking hazard due to their size and shape. 

Salted or flavored cashews are especially dangerous because the added sodium or seasonings can be toxic to cats. So, while cashews might be a delightful snack for you, it’s best to keep them away from your feline friend.

6. Pistachios

Pistachios are another nut that should be kept out of your cat’s reach. Pistachios are not toxic to cats, but like most nuts, they are rich in fats and oils, which are difficult for cats to digest. 

Cats who eat pistachios may experience stomach upset, vomiting, or diarrhea, and regular consumption could lead to more serious issues like obesity or pancreatitis. Pistachios also present a significant choking hazard due to their small size and hard shell. 

It’s important to remember that many pistachios are sold salted or flavored, which adds an additional layer of risk. Salt is especially harmful to cats and can lead to sodium poisoning, which can cause symptoms like vomiting, diarrhea, lethargy, and seizures. For these reasons, pistachios should never be part of a cat’s diet.

7. Hazelnuts

Hazelnuts, while not as commonly discussed in terms of pet safety, should also be avoided for cats. Hazelnuts are not toxic but carry the same risks as other nuts. ‘

They are high in fats, which can lead to digestive upset and the risk of pancreatitis. Hazelnuts are also large and hard, posing a choking hazard, especially for small cats. 

Additionally, flavored or sweetened hazelnuts (such as those found in snacks or spreads) often contain harmful additives like sugar or salt. Due to the potential health risks, it’s best to steer clear of hazelnuts as a treat for your cat.

8. Walnuts

Lastly, let’s revisit walnuts. While not toxic, walnuts are particularly high in fats and oils, making them difficult for your cat to digest. Regular consumption of walnuts could lead to digestive issues, obesity, and even pancreatitis. 

Additionally, the large size and hard texture of walnuts make them a choking hazard for cats. And if walnuts are flavored or coated in anything sweet or salty, they could be even more harmful. Given the potential risks, it’s best to avoid feeding your cat walnuts or any other nuts.

Can cats eat walnut seeds?

When it comes to feline nutrition, you might wonder, Can cats eat walnut seeds? The answer is no; walnut seeds are not safe for cats to consume.

Walnuts themselves, which are technically seeds, pose several health risks for cats. They are high in fat, making them difficult for cats to digest. 

Consuming walnut seeds can lead to gastrointestinal upset, including vomiting and diarrhea. The large size and hard texture of walnut seeds also present a choking hazard, particularly for smaller cats.

Additionally, while walnut seeds aren’t toxic to cats, they can contribute to obesity and pancreatitis if eaten regularly due to their high-fat content. It’s essential to prioritize your cat’s health by providing a balanced diet that meets their nutritional needs without including potentially harmful foods like walnut seeds.

Why Are Walnuts Bad for Cats?

Walnuts may seem harmless, but they pose several risks to our feline friends. Here’s a breakdown of why walnuts are bad for cats:

1. High Fat Content
Walnuts are high in fats, which can be challenging for cats to digest. Cats are obligate carnivores, meaning their digestive systems are not designed to process high-fat plant materials. Consuming walnuts can lead to gastrointestinal upset, including vomiting and diarrhea.

2. Potential for Pancreatitis
Regular consumption of high-fat foods like walnuts can increase the risk of pancreatitis, a severe inflammation of the pancreas. Your cat may experience stomach pain, throw up, and seem unusually tired. This condition requires immediate veterinary attention.

3. Choking Hazard
The size and hard texture of walnuts make them a choking hazard for cats. Smaller cats are particularly at risk, as they may struggle to chew or swallow walnuts safely.

4. Non-toxic but Unsafe
While walnuts are not toxic to cats, they do not offer any nutritional benefits. Feeding your cat foods that provide no value can lead to poor dietary choices and health issues over time.

5. Flavored or Coated Walnuts
Many walnuts are sold salted or coated with various seasonings. These additives can be harmful to cats. Excessive sodium can lead to sodium poisoning, causing symptoms like vomiting, diarrhea, and lethargy.

6. Potential for Toxic Mold
Walnuts can sometimes develop a type of mold called Aspergillus, which produces a toxin known as aflatoxin. Ingesting moldy walnuts can lead to serious health problems, including liver damage.

What to Do If Your Cat Eats Walnuts?

So, what if the worst happens? What if your curious cat manages to sneak a walnut or two before you can stop them?

Here’s what you should do:

1. Monitor Your Cat: If your cat eats walnuts, keep a close eye on them for the next 24 to 48 hours. Look for any signs of digestive upset, such as vomiting, diarrhea, lethargy, or a refusal to eat. Cats can be good at hiding discomfort, so pay attention to subtle changes in behavior.

2. Offer Water: Encourage your cat to drink plenty of water. This can help flush out any oils or fats from the walnuts and prevent dehydration if your cat experiences vomiting or diarrhea.

3. Remove Any Remaining Walnuts: If your cat got into a bowl of walnuts or knocked some off the counter, make sure to remove any remaining walnuts to prevent further snacking.

4. Contact a Vet: If your cat starts showing signs of distress—especially vomiting, diarrhea, or lethargy—it’s a good idea to contact a vet for advice. While a small amount of walnut might not cause a serious issue, it’s always better to be safe than sorry.

How to Prevent Your Cat from Eating Walnuts

Prevention is key to keeping your cat safe from the risks of eating walnuts. Here are some practical steps to take:

1. Keep Walnuts Out of Reach
   Store walnuts in sealed containers or cabinets that your cat can’t access. Cats are naturally curious, and leaving nuts in places like countertops or tables can make them easy targets.
2. Avoid Leaving Snacks Unattended
   Whether it’s a bowl of walnuts or mixed nuts, never leave snacks unattended around your cat. Cats are opportunistic and may try to nibble on what they find.
3. Provide Cat-Friendly Snacks
   Offer your cat safe, nutritious treats instead. Cat-friendly snacks like cooked chicken, tuna, or commercial cat treats will keep them satisfied and less curious about human food.
4. Supervise Meal Times
   If you’re eating walnuts or any snacks, keep an eye on your cat. Some cats may try to steal food from your plate, so it’s best to prevent this behavior by supervising meal times.

By keeping walnuts out of your cat’s reach and providing them with safe alternatives, you can ensure they stay healthy and avoid any potential dangers.
