Can cats eat sugar syrup?

Cats have a sweet tooth just like humans, so it’s understandable why a cat might be tempted by sugary treats like syrup. However, sugar syrup and other sugary foods are not recommended for cats. Feeding cats too much sugar can lead to obesity, diabetes, dental problems, and other health issues. Here’s a quick overview of whether cats can safely eat sugar syrup.

Quick Answer

No, cats should not eat sugar syrup. While small amounts of sugar syrup likely won’t cause immediate harm, regular consumption can lead to obesity, diabetes, dental disease, gastrointestinal upset, and other health problems in cats.

Can Cats Taste Sugar?

Yes, cats can taste sugar and do enjoy sweet flavors. Cats have taste receptors for five basic tastes: sweet, sour, salty, bitter, and umami. Of these tastes, cats respond most strongly to bitter tastes and also have a well-developed sense of sweet taste.

In the wild, cats don’t tend to encounter much sugar in their natural diets based on hunting prey animals and eating meat. But as domesticated pets, cats will readily eat sugary foods if given the chance.

Do Cats Like Sugar?

Most cats seem to enjoy the taste of sugar and will seek out sugary foods. A preference for sweet flavors is likely an evolutionary advantage as sugar provides a concentrated source of energy. Unfortunately, this attraction to sugar can lead cats to overindulge when given the chance.

Cats may be strongly attracted to syrup because it is very sweet and has a thick, viscous texture unlike other foods they normally eat. The sweet aroma and taste combined with the syrup’s appearance and texture can make it very enticing to cats.

Is Sugar Syrup Toxic to Cats?

Pure sugar syrup is not directly toxic to cats. However, feeding sugar syrup to cats on a regular basis can lead to many harmful effects. Consuming too much sugar long-term can contribute to obesity, diabetes, dental cavities and periodontal disease, gastrointestinal issues, hyperactivity, immune system problems, and more.

Health Risks of Cats Eating Sugar Syrup

Some specific health risks of sugar syrup for cats include:

  • Obesity: Sugar syrup is very high in calories and sugar. Feeding syrup frequently can lead to rapid weight gain and obesity.
  • Diabetes: Excess sugar intake makes cats more prone to developing diabetes. Diabetes is a serious disease that requires lifelong insulin injections and diet management.
  • Dental disease: Sugar helps bacteria multiply in the mouth, leading to more plaque, tartar buildup, gingivitis, and dental cavities.
  • Gastrointestinal upset: Too much sugar syrup may cause vomiting, diarrhea, gas, or abdominal pain in some cats.
  • Hyperactivity: Sugar provides a quick energy boost and can make some cats hyperactive and difficult to settle down.
  • Nutritional imbalance: Feeding high-sugar syrup can displace balanced meals, leading to vitamin, mineral, and protein deficiencies.
  • Weakened immunity: Excess sugar intake can negatively impact white blood cells, lowering immunity and resistance to infection.

Can Cats Have a Little Sugar Syrup?

It’s best to avoid giving cats any amount of sugar syrup. Even small portions of syrup can start cats down an unhealthy path of sugar cravings, weight gain, and dental issues. There are no nutritional benefits of syrup that warrant giving any to cats.

That said, a single lick of syrup or small taste is not likely to cause harm. But this should not become a regular treat. Ideally, the cat’s diet should remain completely free of any added sugar.

Signs of Sugar Overdose in Cats

Cats don’t handle large amounts of sugar well. Signs your cat may have consumed too much sugar syrup or is suffering from sugar overdose can include:

  • Vomiting
  • Diarrhea
  • Extreme thirst (polydipsia)
  • Increased urination (polyuria)
  • Restlessness
  • Hyperactivity
  • Tremors
  • Seizures
  • Disorientation

If your cat displays any of these signs after eating sugar syrup, contact your veterinarian immediately. Prompt treatment can help prevent serious complications.

What to Do If a Cat Eats Sugar Syrup

If you catch your cat lapping up sugar syrup, take these steps:

  1. Remove the syrup right away so the cat can’t continue eating it.
  2. Check how much they ate. Large amounts may require emergency veterinary treatment.
  3. Monitor for signs of GI upset, hyperactivity, or sugar overdose.
  4. Call your vet if concerning symptoms develop.
  5. Make sure the cat has access to plenty of fresh water to help dilute the sugar concentration.
  6. Discourage sugar cravings by not giving table scraps or sweets.
  7. Schedule a veterinary dental cleaning if needed to remove residual sugar from the teeth.

Can Cats Eat Pancake Syrup or Maple Syrup?

It’s best not to share any type of syrup — including pancake syrup, maple syrup, or other flavored syrups — with cats. While the exact sugar content varies, all syrups are concentrated sources of sugar and calories.

Both pancake and maple syrup may appeal to cats due to their sweet flavors and aroma. But neither offers any nutrition benefit for cats. And their high sugar content makes them inappropriate to feed cats on a regular basis.

Pancake Syrup

Pancake syrup is made from corn syrup blended with flavorings and has a very high sugar content. Too much can cause gastrointestinal, dental, weight, and other health issues for cats.

Maple Syrup

100% pure maple syrup comes from the sap of maple trees. It has slightly less sugar than pancake syrup, but is still around 60% sugar by weight. Maple syrup should only be fed to cats rarely in tiny portions, if at all.

Healthy Alternatives to Sugar Syrup for Cats

Instead of sugar syrup, feed your cat a healthy balanced diet and use treats sparingly. Some healthier options include:

  • Canned or raw cat food. Look for grain-free, low-carb varieties.
  • Cooked, unseasoned meat like chicken, fish, or beef.
  • Low-sodium broths or gravies.
  • Catnip, valerian root, or cat grass.
  • Freeze-dried meat or fish treats.

Avoid giving table scraps or people food, which is often high in carbs, fat, sugar, and salt. Read labels carefully and consult your vet for the best diet for your cat’s needs.

Can Kittens Have Sugar Syrup?

No, you should never give sugar syrup to kittens under any circumstances. Kittens have even less ability to metabolize sugar than adult cats.

Kittens also need very specific nutrition to support healthy growth and development. The high sugar content in syrup can lead to diarrhea, malnutrition, obesity, and health problems.

Kittens should eat only kitten formula until around 4-6 weeks of age when they can start transitioning to wet and dry kitten food. Homemade syrup has no place in a growing kitten’s diet.

Can Diabetic Cats Have Sugar Syrup?

Diabetic cats must follow a very strict diet low in carbohydrates and sugar, making sugar syrup off limits. Any amount of syrup can cause blood sugar spikes, interfere with medication, and make diabetes much harder to manage.

Never give syrup to a diabetic cat even if they beg for it. Diabetic cats may have an exaggerated appetite and love for sugary foods. But owners must refrain from sharing sweets and stick to the prescribed veterinary diet.

Is High Fructose Corn Syrup Bad for Cats?

Yes, high fructose corn syrup should be avoided for cats. This added sugar is found in many human snack foods and has no place in a cat’s diet. High fructose corn syrup provides empty calories and sucrose sugars that can harm cats’ health.

Sugar Syrup vs. Honey – Which is Healthier for Cats?

Neither sugar syrup nor honey is healthy for cats when given in more than tiny amounts. Both are concentrated sources of sugar with no redeeming nutritional value for cats.

Of the two, pure honey may be slightly better tolerated since it has some antioxidants and trace nutrients. But honey is still around 80% sugar and too much can also cause obesity, diabetes, and dental disease.

For optimal health, cats should get sugar only from whole food carbohydrate sources like vegetables. Added sugars like syrup and honey should be avoided.

How Much Sugar Syrup is Safe For Cats?

No amount of sugar syrup can be considered 100% safe for cats. Even small doses of syrup can accustom cats to sweet flavors and lead to sugar cravings.

For optimal health, cats should not have any syrup at all. At most, a teaspoon of syrup once or twice a year is unlikely to cause lasting harm. But never make it a regular treat.

To avoid problems, keep cats away from any sources of syrup. Cats should not ingest syrup meant for human foods or desserts.

Cat-Safe Sugar Substitutes

To satisfy your cat’s sweet tooth safely, use cat-friendly sugar substitutes like:

  • Freeze-dried meat pieces
  • Freeze-dried fish flakes
  • Bonito flakes
  • Coconut flakes
  • Pet-safe jerky treats

Look for treats made with natural ingredients and minimal additives. Check the calorie count as well, since even healthy treats can add calories.

Treats should make up no more than 10% of a cat’s daily calories. Use portion control and save treats for occasional use as training rewards or enrichment.

Cat Snacks and Treats Without Sugar

Some healthy snack options for cats that are naturally sugar-free include:

  • Chicken or beef broth ice cubes
  • Freeze-dried chicken, fish, or liver
  • Dental treats with limited ingredients
  • Chicken breast
  • Tuna flakes packed in water
  • Air-popped popcorn (no butter or salt)
  • Baked unseasoned meat or fish

Check labels to make sure treats do not contain sugar, corn syrup, honey, fructose, sucrose, dextrose, or other added sweeteners. Avoid giving table scraps or human sweets, which are unsuitable for cats.

Can Cats Eat Sugar Free Syrup?

Sugar-free syrup made with artificial sweeteners like Splenda or aspartame is also not recommended for cats. While the sugar is removed, the artificial sweeteners are not necessarily safe for cats.

Little research has been done on artificial sweeteners’ effects in cats. However, side effects like cancer have been found in lab animals. It is best not to experiment with sugar substitutes made for humans.

Additionally, sugar-free syrup still contains very few nutrients and unnecessary calories for cats. It provides no benefit and may pose risks from additives.

Can Cats Eat Chocolate Syrup?

No, chocolate syrup should never be given to cats. Chocolate contains the stimulant theobromine, which is toxic to cats.

Just a small amount of chocolate can make cats seriously ill. Signs of theobromine poisoning include:

  • Vomiting
  • Diarrhea
  • Increased heart rate
  • Restlessness
  • Muscle tremors
  • Seizures
  • Coma
  • Death

Darker chocolate contains more theobromine and is more toxic. But all chocolate and cocoa products, including chocolate syrup, should be kept away from cats.

Can Cats Eat Caramel Syrup?

Caramel syrup should also be avoided for cats. While not toxic like chocolate, the high sugar content can contribute to obesity, diabetes, and dental disease.

Caramel syrup is made from cooking sugar, butter, and cream to create a smooth, sweet syrup. The high calorie and fat content provides empty calories without nutrition.

For a similar texture without the sugar, try offering meat or bone broth frozen into ice cubes for cats to lick safely.

Can Cats Have Strawberry Syrup?

Strawberry syrup is high in sugar and should not be given to cats. A tiny amount will not cause immediate harm. But strawberry syrup offers no nutrition and too much sugar is unhealthy.

Some sugar-free strawberry syrups made with artificial sweetener may also be unsafe. It is best to avoid flavored syrups altogether and stick to cat foods and treats formulated specifically for cats.

Can Cats Eat Blueberry Syrup?

Blueberry syrup is not recommended for cats primarily due to its high sugar concentration. The blueberries themselves are healthy, but juicing them into a syrup concentrates the sugar.

Small amounts of plain fresh or frozen blueberries can be an occasional treat for cats. But stick to just a few berries at a time.


Sugar syrup should not be a regular part of a cat’s diet. While a small taste may not cause immediate harm, regular consumption of syrup can lead to obesity, diabetes, dental disease, GI issues, and other problems.

For optimal health, avoid giving your cat any table scraps, sweets, or sugary syrups. Stick to high protein, low carb cat foods. Use healthy meat-based treats sparingly. Be vigilant to keep syrups and sweets out of your cats’ reach.

With a balanced diet and plenty of exercise and enrichment, your cat can lead a long, healthy life without any added sugar.
