Can maple syrup harm cats?

Maple syrup is a popular pancake topping and natural sweetener, but is it safe for cats to eat? As cat owners, it’s important to understand which human foods are safe and which should be avoided when it comes to our furry feline friends. This article will examine whether maple syrup can be harmful to cats.

What is maple syrup?

Maple syrup is made from the sap of maple trees, most commonly sugar maple, red maple, and black maple trees. It takes around 40 gallons of maple sap to produce 1 gallon of maple syrup. The sap is boiled down to evaporate the water, leaving behind the concentrated, sugary syrup.

Pure maple syrup contains one ingredient – maple syrup! It has a rich, complex flavor and is approximately 60% sucrose. Maple syrup grades indicate color and flavor, with Grade A being lighter and milder and Grade B being darker and more robust.

Maple syrup contains nutrients like manganese, zinc, calcium, potassium, and iron. However, its main nutritional components are carbohydrates and sugar. Per tablespoon, maple syrup contains:

Nutrition Facts Amount
Calories 52
Carbohydrates 13 g
Sugars 12 g

So while maple syrup offers some micronutrients, its sugar content is quite high.

Are cats able to digest sugar and maple syrup?

Cats’ natural diets consist almost entirely of meat, so they have no dietary need for sugars and carbohydrates. Cats lack the ability to properly digest sugars.

The feline liver is not as efficient at metabolizing large amounts of sugar as the human liver. Cats also have low levels of the enzyme amylase in their saliva, which is used to break down carbohydrates.

So unlike humans who can safely consume moderate amounts of sugar, cats do not process high-sugar foods very effectively. Consuming sugar can be problematic for cats and lead to a number of health issues.

Blood sugar and diabetes

When cats consume a lot of sugar, it causes a rapid spike in blood glucose levels. The excess sugar gets converted into fat by the liver. Over time, this process can lead to obesity, insulin resistance, and eventually feline diabetes.

Diabetes is growing more common in cats, and excessive carbohydrate and sugar intake is a major risk factor. Once cats develop diabetes, they lose their ability to properly regulate blood sugar levels. Lifelong insulin therapy and close monitoring of blood glucose is required to manage the disease.

Dental health

Bacteria and plaque love to feed on sugars. The sugary environment promotes cavity development. Dental disease is extremely common in cats, affecting around 70% of the population. Consuming sugary foods like maple syrup only puts cats at greater risk for dental decay, abscesses, and gum disease.

Gastrointestinal upset

Too much sugar and carbs can cause digestive upset in cats like vomiting, diarrhea, gas, and bloating. The gut microbiome gets thrown off balance, allowing harmful bacteria to proliferate.

Maple syrup’s high osmolality or molecular concentration can also draw water into the intestinal tract via osmosis. This shifts electrolyte balances and alters hydration status, further disrupting GI function.


With a high caloric density and abundant sugars, maple syrup can easily cause unhealthy weight gain in cats. Obese cats are more prone to diabetes, arthritis, heart disease, and many other problems. Sticking to an appropriate low-calorie, low-carb diet is key for maintaining cats’ ideal body weights.

Tooth decay

The sugars in maple syrup can feed bacteria and cause cavities if stuck on cats’ teeth. Cats spend much of their day grooming, so syrup sticking to their fur is likely to end up in their mouths. Dental infections are common and painful in cats, so avoiding sugary foods is wise.

Are there any benefits to maple syrup for cats?

Given that cats have no biological requirement for sugar and maple syrup provides no essential nutrients for felines, there are no direct benefits to cats consuming maple syrup.

Small amounts of maple syrup may be safe for cats to ingest occasionally, but it offers no health benefits. The risks tend to outweigh any potential rewards.

Some holistic veterinarians may suggest small doses of maple syrup to treat constipation in cats. As a natural laxative, the sugars pull water into the colon to soften stools. However, this laxative effect could also cause diarrhea, so other remedies are likely safer.

Overall, it’s best to view maple syrup as an unnecessary, potentially harmful treat for cats.

Can maple syrup poisoning occur in cats?

Maple syrup is unlikely to cause acute poisoning in cats when consumed in small amounts. However, it can make cats quite sick if large volumes are ingested.

Signs of maple syrup poisoning in cats may include:

  • Vomiting
  • Diarrhea
  • Excessive thirst and urination
  • Loss of appetite
  • Lethargy
  • Tremors
  • Seizures
  • Coma

These effects occur because maple syrup’s high sugar content can drastically impact feline digestion, hormone regulation, hydration, electrolyte balance, and neurological function.

If maple syrup poisoning is suspected, immediate veterinary treatment is vital. Aggressive sugar and fluid management therapy is required to stabilize cats in this emergency scenario. The prognosis largely depends on how quickly treatment can be initiated.

How much maple syrup is toxic to cats?

No definitive toxic dosage has been established for maple syrup in cats. Factors like the individual cat’s size and health status will influence their tolerance. However, we know cats do not handle sugar well, so even small amounts could cause issues.

As a general guideline, ingestion of more than one teaspoon of maple syrup may put cats at risk for gastrointestinal, metabolic, and neurological side effects. Consuming more than a tablespoon of maple syrup can potentially be very dangerous for a cat depending on its body weight.

To put it in terms of sugar content, a teaspoon of maple syrup contains around 4 grams of sugar and 20 calories. This is already a significant amount of sugar for a cat-sized stomach to handle.

Larger doses flooding a cat’s system with excess simple sugars could be toxic. It’s best to avoid giving cats anything more than a taste or lick of pancake syrup.

What should you do if your cat eats maple syrup?

Check how much maple syrup your cat managed to ingest. If it was just a tiny amount, monitor them closely for signs of stomach upset like vomiting or diarrhea. Withhold food for several hours to allow their digestive system to reset.

If your cat consumed more than a taste or lick of syrup, immediately contact your veterinarian or the ASPCA Poison Control Center for guidance. Depending on the amount ingested and your cat’s size and health, the vet may advise you to induce vomiting at home or bring your cat into the clinic for evaluation and decontamination treatment.

Always better to be safe than sorry! Even if your cat seems fine after eating maple syrup, let your vet know so they can properly assess any risks. Monitoring blood sugar is wise after significant syrup ingestion.

Only induce vomiting if your vet recommends and provides instructions on how to do so safely. Never give hydrogen peroxide or force vomiting without speaking to a professional first.

How can I keep maple syrup away from my cat?

The best way to prevent maple syrup issues is to keep it away from your cats in the first place. Follow these tips to maple-syrup proof your home:

  • Store away in tightly sealed containers out of paw’s reach
  • Never leave maple syrup unattended in eating areas
  • Clean up spills immediately
  • Avoid placing syrup containers on counter edges or tables where cats jump
  • Be extra careful when cooking or prepping with syrup
  • Wait until pancakes cool to syrup, so all gets absorbed
  • Rinse dishes and utensils that contained syrup before leaving in sink

You can also provide cats with safer, pet-friendly syrup alternatives like glycerin-based products. Read labels and consult your vet.

What other sugary human foods are bad for cats?

Maple syrup certainly isn’t the only human food containing problematic amounts of sugar for cats. Here are some other sugary foods to avoid feeding cats:

  • Candy
  • Cookies
  • Cake
  • Pies
  • Soda
  • Fruit juice
  • Honey
  • Jams and jellies
  • Fruit with heavy syrup
  • Sweetened yogurt
  • Flavored syrups
  • Sugary breakfast cereals
  • Desserts
  • Chocolate

Basically, be very sparing with treats containing added sugars, and never give cats homemade baked goods or other sugary foods meant for human consumption. Even natural sugars like in fruit must be fed cautiously and in moderation.

What foods are safe for cats?

The healthiest diet for cats primarily consists of a balanced wet or dry commercial cat food. Beyond that, cats can enjoy small amounts of:

  • Plain cooked chicken or turkey (no bones or skin)
  • Plain boiled fish like salmon, tilapia or cod (no seasoning)
  • Hard boiled eggs
  • Cottage cheese or plain yogurt
  • Low-sodium vegetable broths
  • Finely chopped or pureed vegetables like carrots or peas
  • Small pieces of fruits like bananas, apples or berries
  • Plain cooked beans, rice or pasta
  • Cat grass
  • Pet treats without added sugars

Always slowly introduce new foods and monitor cats for any digestive upset. Limit people food to just 10% of their total caloric intake at most.


While tiny tastes of pancake syrup won’t harm healthy cats, it offers no nutritional benefits and risks causing digestive woes, tooth decay, blood sugar spikes, unhealthy weight gain and toxicity. It’s safest to keep maple syrup and other sugary human foods away from cats. Read labels carefully and ask your vet if you ever have any questions about which foods are feline-approved. With some simple precautions, you can keep your cats content and healthy while still enjoying sweet breakfast treats yourself!
