Can Squirrels Eat Chocolate? (Risks and Realities)

As a nature lover who has spent years observing and interacting with squirrels, I often get asked – Can squirrels eat chocolate? It’s a common question, especially for those who enjoy feeding the bushy-tailed critters in their backyards.

Squirrels have the capacity to eat chocolate, but it’s important to note that chocolate contains substances like theobromine and caffeine. When consumed in large quantities, these substances can be toxic and harmful to squirrels. So chocolate is not recommended for squirrels.

In this guide, we’ll dive deep into all aspects of chocolate consumption for squirrels – the health effects, safe quantities, signs of poisoning, and healthier alternatives to chocolate treats.

Can squirrels eat chocolate? Is it Toxic?

While, in principle, squirrels can have chocolate, it is not healthy for them. Chocolate contains methylxanthines. Notably among them are theobromine and caffeine. While humans can metabolize them quickly, squirrels and other animals cannot.

For squirrels, even a small quantity of theobromine can be poisonous. An average 100g bar of dark chocolate may contain up to 200 mg of theobromine. So even a tiny piece can be toxic to a squirrel weighing 0.5 lbs.

Consuming chocolate can have severe consequences for squirrels, as it can lead to Theobromine poisoning. This toxic reaction may manifest in various distressing symptoms such as tremors, diarrhea, seizures, and in the most extreme cases, even mortality. The darker the chocolate, the more concentrated the theobromine.

How Much Chocolate Can a Squirrel Safely Eat?

There is no established “safe” amount of chocolate for squirrels. Various factors contribute to the level of toxicity in relation to chocolate consumption, including:

  • Type of chocolate (dark vs. milk vs. white)
  • Body weight of the squirrel
  • Metabolism and sensitivity of the individual

As a general rule, the less chocolate a squirrel eats, the better. An occasional small piece of chocolate may not cause issues. But feeding sizeable quantities of any chocolate product is risky.

Can Squirrels Have White Chocolate?

White chocolate has very little actual cocoa solids, and hence negligible theobromine. But it is still high in sugar and fat, which can cause digestive upsets in squirrels when eaten in large amounts.

Overall, white chocolate holds no nutritional value for squirrels. It is better to avoid feeding it altogether.

Signs of Chocolate Poisoning in Squirrels

Look out for these symptoms if you suspect a squirrel has ingested too much chocolate:

  • Vomiting – One of the earliest signs of chocolate toxicity
  • Diarrhea – Loose stools indicate gastrointestinal distress
  • Increased urination – Theobromine acts as a diuretic leading to increased peeing
  • Hyperactivity – Increased heart rate, and restlessness caused by methylxanthines
  • Muscle tremors – Uncontrolled shaking motions of the face, limbs, or tail
  • Seizures – In severe cases, seizures preceding death

Steps to Take if a Squirrel Consumes Chocolate

If you see a squirrel consuming chocolate, try to take the food away gently without stressing the animal further.

If you observe any worrisome symptoms in a squirrel, it is crucial to promptly contact a wildlife rehabilitator for assistance. They may try to induce vomiting or give activated charcoal to absorb toxins.

With prompt vet care, chocolate poisoning is treatable if caught early. However, the prognosis declines rapidly once seizures or extreme symptoms manifest.

The Adverse Effects of Chocolate on Squirrels

Let’s go over some key reasons why chocolate and its derivatives can be dangerous for squirrels:

High Theobromine and Caffeine Content

As mentioned earlier, chocolate contains theobromine and caffeine. Squirrels lack the enzymes needed to break down these compounds quickly.

Theobromine has a narrow margin between therapeutic and toxic doses. Caffeine acts as a stimulant leading to hyperactivity at moderate doses.

Gastrointestinal Problems

Chocolate contains insoluble particles like starch, cellulose, and fat that squirrels cannot digest properly. This leads to stomach upsets, cramping, diarrhea, and loss of nutrients.

Unhealthy Sugars and Fats

Chocolate is high in sugar and saturated fats – most coming from cocoa butter. Too much can cause weight gain, nutritional imbalance, and chronic issues like diabetes in squirrels.

Lack of Nutritional Value

Chocolate provides no proteins, essential fatty acids, vitamins, or minerals that squirrels need in their diet. It only supplies “empty calories” from sugar and fat.

Healthy Alternatives to Chocolate for Squirrels

Instead of chocolate, provide squirrels with safe, nutritious foods that align with their natural diets. But, what do squirrels eat? Here are some healthy treats you can offer:

Fruits and Vegetables

Squirrels enjoy nibbling on berry fruits like blueberries, blackberries, and strawberries. Core fruits like apples and pears are also excellent choices.

For vegetables, pick vitamin-rich leafy greens like kale, lettuce, and spinach (in moderation). Squirrels also like broccoli, peas, and roasted squash.

Nuts and Seeds

Walnuts, almonds, pecans – nuts both in and out of shells make great squirrel treats. Just ensure they are fresh and unsalted.

Go for raw, unflavored seeds like pumpkin, sunflower, and flax seeds. Give variety to keep their diet balanced.

Whole Grains

Try puffed rice, wheat, millet, or multi-grain cereals low in sugar. Scatter them minimally in the yard or use them in DIY feeders.

Avoid processed snack foods like popcorn, corn chips, or sugary breakfast cereals.

Natural Protein Sources

Dried insects like mealworms offer protein without unhealthy additives. Just a teaspoon 2-3 times a week is sufficient.

Unsweetened Greek yogurt and small cubes of mild cheese are other options.

Clean Water

Ensure fresh, clean drinking water is always available. Change it daily and keep feed areas dry.

Pro Tips to Keep Squirrels Safe

Here are some extra tips to prevent chocolate exposure and keep your backyard squirrels healthy:

  • Never hand-feed chocolate or other human foods to wild squirrels.
  • Clean up any food scraps like candy wrappers, cake crumbs, etc.
  • Use trash cans with tight lids to avoid squirrels scavenging for chocolate.
  • Keep chocolate bait boxes away from areas where squirrels frequent.
  • Check ingredients on squirrel feed mixes – avoid cocoa powder.
  • Discourage dependence on humans for food to prevent bad dietary habits.


Can squirrels eat chocolate? It is best not to feed any chocolate to squirrels intentionally. The theobromine and caffeine can be toxic, especially when consumed regularly.

Dark chocolate poses the highest risk, but even milk chocolate can be harmful in large quantities. White chocolate is not as dangerous but still unhealthy.

If a squirrel accidentally eats chocolate, monitor it for concerning symptoms and call a vet if needed. Inducing vomiting may help rid toxins.

Stick to natural, nutritious foods that align with a squirrel’s native diet. Fruits, veggies, nuts, seeds, and insects are great alternatives to chocolate for occasional treats.

With some care and common sense, we can keep backyard squirrels happy and chocolate-free!
