As cute and mischievous as raccoons can be, those adorable little masked bandits are still wild animals. And like most wild animals, there are certain foods that raccoons should steer clear of – chocolate being one of them.

Chocolate is toxic to raccoons and can make them very sick or even potentially kill them if they consume too much of it. But why exactly is chocolate so dangerous for these furry little creatures? Let’s take a closer look.

The Toxic Culprit: Theobromine

The reason chocolate is poisonous to raccoons (and many other animals including dogs and cats) is because it contains a substance called theobromine. Theobromine is a bitter alkaloid compound that occurs naturally in the cacao plant, which is used to make chocolate.

While theobromine isn’t extremely toxic to humans since our bodies can metabolize and excrete it relatively easily, the same can’t be said for raccoons and many other animals. Raccoons metabolize theobromine very slowly, allowing it to quickly build up to toxic levels in their bloodstream after ingestion.

At high enough doses, theobromine can cause a range of symptoms in raccoons including:

• Vomiting
• Diarrhea
• Increased heart rate
• Restlessness
• Muscle tremors
• Seizures
• Internal bleeding
• Heart failure

In severe cases, an overdose of theobromine from eating too much chocolate can be fatal for a raccoon. The darker and more bitter the chocolate, the higher the theobromine content, making dark and baking chocolates particularly dangerous compared to milk chocolate.

How Much Is Too Much?

So just how much chocolate would it take to seriously harm or potentially kill a raccoon? The toxic dose can vary based on factors like the raccoon’s size, age, and overall health. But in general:

• As little as 2-3 ounces of milk chocolate could be toxic to an average adult raccoon
• Just 1 ounce or less of dark or baking chocolate could prove fatal

To put those numbers in perspective, a standard milk chocolate candy bar is around 1.5 ounces. So even a relatively small amount of chocolate can spell serious trouble for a raccoon that gets into it.

The Symptoms of Chocolate Toxicity

If a raccoon does ingest a toxic amount of chocolate, the symptoms can set in relatively quickly – usually within 6-12 hours after consumption. Early symptoms may include:

• Vomiting
• Diarrhea
• Increased thirst
• Restlessness and hyperactivity

As the chocolate toxicity progresses over the next 12-36 hours, more severe neurological and cardiac symptoms can develop such as:

• Muscle tremors and seizures
• Elevated heart rate
• Abnormal heart rhythm
• Internal bleeding

Unfortunately, by the time these severe neurological and cardiac symptoms set in, the prognosis is often poor even with veterinary treatment. The sooner chocolate toxicity is recognized and treated, the better the chances of recovery.

What To Do If You Suspect Chocolate Ingestion

If you ever suspect a raccoon has eaten chocolate, it’s crucial to seek veterinary care immediately – even if you’re unsure exactly how much chocolate the raccoon consumed. The veterinarian may be able to induce vomiting and give activated charcoal to help bind any remaining theobromine in the digestive tract.

IV fluids, anti-seizure medications, drugs to control heart rate and rhythm, and other supportive care may also be needed depending on the severity of the chocolate toxicity. The sooner treatment begins, the better the odds of recovery.

Keeping Raccoons Safe From Chocolate

The best way to prevent a run-in with chocolate toxicity is to ensure any chocolate products in your home are kept safely out of reach of any raccoons. This includes:

• Keeping all chocolate stored in airtight, raccoon-proof containers
• Not leaving any chocolate products out on counters or tables
• Promptly cleaning up any spills or crumbs containing chocolate
• Using raccoon-proof lids or locks on indoor and outdoor trash cans

If you do end up with a nighttime visitor raiding your kitchen for sweets, it’s best to gently shoo the raccoon away without leaving any chocolate treats behind as a “parting gift.”

While those cute raccoon antics may be amusing to watch from a safe distance, it’s not worth risking a potentially deadly bout of chocolate poisoning. So do both your family and your local raccoon population a favor by keeping all chocolate safely contained and out of reach.

By understanding the very real dangers that chocolate poses to these woodland creatures, we can all do our part to keep local raccoon populations safe and healthy – while still being able to indulge our own cravings for the sweet stuff.
