Pistachios and Squirrels: Common Myths and Facts

In the intricate world of nature, the diet of squirrels has always been a subject of curiosity and fascination. These agile and spirited creatures are known for their varied and adaptable eating habits, with a particular fondness for nuts. 

This article delves into an intriguing question: Can squirrels eat pistachios? It’s a query that not only interests wildlife enthusiasts and pet owners but also sheds light on the broader aspects of wildlife nutrition and care.

As we explore this topic, we’ll journey through the nutritional landscape of pistachios, uncovering their benefits and potential risks when included in a squirrel’s diet. Understanding the dietary preferences and needs of these playful animals helps us appreciate the delicate balance of nature and the importance of responsible wildlife feeding practices.

Nutritional Information of Pistachios

Pistachios are more than just a tasty treat; they’re a powerhouse of nutrition. Packed with protein, these nuts provide essential amino acids crucial for a squirrel’s muscle development and maintenance. 

High in fiber, pistachios aid in digestive health, ensuring that our furry friends maintain a smooth and healthy digestive process.

But the benefits don’t stop there. These nuts are rich in vitamins, particularly B6, which plays a vital role in the functioning of a squirrel’s nervous system, and vitamin E, an antioxidant that helps protect their cells from damage. The mineral content in pistachios, including potassium and magnesium, contributes to the overall well-being of squirrels, supporting bone health and energy production.

Are Pistachios Safe for Squirrels?

When it comes to feeding squirrels, safety is a top priority. Fortunately, pistachios, when offered in moderation, are a safe snack. They are non-toxic to squirrels and, in fact, offer several health benefits. However, it’s important to note that like any food, pistachios should be given in balance as part of a diverse diet.

Pistachios, with their high nutritional content, not only satisfy hunger but also contribute to the overall health of squirrels. Their protein and fiber content are particularly beneficial. But, moderation is key. Overfeeding pistachios can lead to health problems, just like with any other food.

Potential Risks of Feeding Pistachios to Squirrels

Despite their benefits, there are risks associated with feeding pistachios to squirrels. One major concern is gastrointestinal upset. Squirrels, though adaptable, have sensitive digestive systems. An excessive amount of pistachios can cause stomach upset or even diarrhea.

Another risk is sodium poisoning. While squirrels can safely consume pistachios, salted varieties should be avoided. Excessive salt intake in squirrels can lead to dehydration, sodium ion poisoning, and other related health issues. Lastly, the issue of weight gain cannot be ignored. Pistachios, being high in fats, can lead to obesity if fed in large quantities.

Variety Matters: Which Pistachios Are Best for Squirrels?

When choosing pistachios for squirrels, the natural, unsalted variety is the way to go. Raw pistachios are preferable as they are free from added oils and salts that can harm squirrels. 

As for pistachios in the shell, they are generally safe, and the process of cracking the shell can be a stimulating activity for squirrels. However, it’s important to ensure that the shells are not treated with any chemicals or pesticides.

Feeding Habits and Preferences

Squirrels are not just random foragers; they have specific feeding habits and preferences. When it comes to pistachios, squirrels show a remarkable fondness for them. They are often seen enthusiastically gnawing at these nuts, enjoying both the nut itself and the challenge of cracking open the shell.

In terms of feeding practices, it’s best to offer pistachios to squirrels as part of a varied diet. While young squirrels might need softer foods, adults can easily handle harder nuts like pistachios. 

It’s important to remember that squirrels’ dietary needs can change with the seasons, and their intake of certain foods, including pistachios, should be adjusted accordingly.

Alternative Nut Options for Squirrels

While pistachios are a great option, diversity is key in a squirrel’s diet. Other nuts that are safe and loved by squirrels include almonds, walnuts, and hazelnuts. Each of these nuts provides different nutritional benefits, contributing to a well-rounded diet. However, it’s crucial to avoid feeding squirrels any nuts that are salted or flavored, as these can be harmful to their health.

Can Baby Squirrels Have Pistachios?

When it comes to baby squirrels, their diet should be approached with caution. Baby squirrels typically need a diet rich in proteins and fats for growth, but their digestive systems are more delicate. Therefore, pistachios should be introduced slowly and in small quantities, ensuring they are unsalted and easy to chew.

When Not To Feed Squirrels Pistachios?

There are certain situations when it’s best to avoid feeding pistachios to squirrels. Overconsumption is a primary concern, as it can lead to the health issues previously mentioned. Additionally, if the pistachios are of the red variety, which may contain added dyes and salts, they should be avoided entirely.

What Nuts Squirrels Cannot Eat?

While squirrels are known for their love of various nuts, including pistachios, there are certain nuts that should be avoided in their diet. Understanding these restrictions is crucial for anyone looking to feed squirrels, whether in a wildlife setting or as pets.

  • Macadamia Nuts: These nuts are known to be toxic to many animals, including squirrels. They can cause adverse health effects, so it’s best to keep macadamia nuts far away from squirrels’ reach.
  • Salted or Flavored Nuts: Any nuts that have been salted, seasoned, or flavored are not suitable for squirrels. These additives can lead to health issues like sodium poisoning, which we’ve discussed earlier, and can disrupt their natural diet balance.
  • Chocolate-Covered Nuts: Chocolate is toxic to many animals, squirrels included. Therefore, chocolate-covered nuts should never be given to squirrels.
  • Almonds (In Large Quantities): While squirrels can eat almonds, they should only be given in moderation. Bitter almonds, in particular, can be harmful due to their cyanide content.
  • Processed Nuts: Any nuts that have been heavily processed, such as those roasted with added oils, should be avoided. These processing methods can strip the nuts of their natural benefits and introduce harmful substances.


In conclusion, pistachios can be a healthy and enjoyable part of a squirrel’s diet, provided they are offered in moderation and as part of a diverse nutritional plan. The key is to ensure that the pistachios are natural, unsalted, and appropriate for the age of the squirrel. 

By understanding the nutritional benefits, potential risks, and appropriate feeding practices, we can responsibly enjoy the sight of these playful creatures relishing their nutty treats.
