Can Cats Have Marshmallows?

The answer is technically yes, cats can eat marshmallows without causing immediate toxicity. Marshmallows are not inherently poisonous to cats, but they are not a suitable treat for our feline friends. Cats have specific dietary needs as obligate carnivores, meaning their natural diet should primarily consist of meat-based proteins and fats. Marshmallows, on the other hand, are made primarily of sugar, corn syrup, and gelatin, providing no nutritional benefit to cats.

The high sugar content in marshmallows can lead to potential health issues for cats, such as obesity, diabetes, and dental problems. Additionally, some marshmallow brands may contain artificial sweeteners, like xylitol, which is highly toxic to cats even in small amounts. Xylitol can cause a rapid drop in a cat’s blood sugar levels, leading to severe symptoms and even death.

For these reasons, it is best to avoid feeding marshmallows to your feline companion and instead opt for treats that are specifically formulated for cats and align with their dietary needs.

Risks and Dangers of Feeding Marshmallows to Cats

Feeding marshmallows to cats can pose several risks and dangers:

  1. Obesity: Marshmallows are high in sugar and calories, which can contribute to obesity in cats if consumed regularly. Obesity can lead to various health issues, including joint problems, heart disease, and diabetes.
  2. Diabetes: The sugary content in marshmallows can lead to insulin resistance and increase the risk of diabetes in cats, a condition that can be challenging to manage in felines.
  3. Dental Problems: The high sugar content in marshmallows can promote tooth decay and dental issues in cats, leading to pain and discomfort.
  4. Digestive Upset: Cats’ digestive systems are not designed to process large amounts of sugar and can lead to digestive upset, including diarrhea and vomiting.
  5. Xylitol Toxicity: Some marshmallow brands may contain xylitol, an artificial sweetener that is highly toxic to cats and can cause life-threatening hypoglycemia (low blood sugar levels).

Why Do Some Cats Like Marshmallows?

It is not uncommon for some cats to show curiosity towards marshmallows due to their texture and smell. Cats are naturally curious creatures and may investigate new objects or food items presented to them. The soft and fluffy texture of marshmallows may pique a cat’s interest, leading them to sniff or paw at the treat.

However, just because a cat shows interest in marshmallows does not mean it is safe or suitable for consumption. Cats may be attracted to the smell and texture of marshmallows, but it is essential to resist the temptation to share this sweet treat with them.

Can Cats and Dogs Have Marshmallows?

Both cats and dogs should avoid consuming marshmallows for the same reasons mentioned earlier. While marshmallows are not toxic in small amounts, they are not a healthy or appropriate treat for either species. Dogs, like cats, are carnivores with specific dietary needs, and the sugary content in marshmallows can lead to similar health issues in canines.

Furthermore, as mentioned before, some marshmallow brands may contain xylitol, which is extremely toxic to dogs as well as cats. Therefore, it is crucial to keep marshmallows out of reach from both cats and dogs to prevent any accidental ingestion.

Sweets That Are Toxic to Cats

While marshmallows themselves are not toxic, it is essential to be aware of other sweets and treats that can be harmful to cats. Some sweets that are toxic to cats include:

  1. Chocolate: Chocolate contains theobromine and caffeine, both of which are toxic to cats and can cause vomiting, diarrhea, rapid breathing, and even seizures and death.
  2. Grapes and Raisins: Grapes and raisins can cause kidney failure in cats, leading to symptoms like vomiting, diarrhea, and decreased urine output.
  3. Xylitol: As mentioned earlier, xylitol is highly toxic to cats and can cause severe hypoglycemia, leading to weakness, lethargy, and seizures.
  4. Alcohol: Alcohol can cause intoxication in cats, leading to loss of coordination, vomiting, and even respiratory failure.
  5. Caffeine: Caffeine can be fatal to cats and can cause symptoms like rapid breathing, heart palpitations, and tremors.

It is essential to keep all sweets and potentially toxic foods out of your cat’s reach and stick to cat-specific treats that are safe and suitable for their dietary needs.

FAQs (Frequently Asked Questions)

1. My cat ate a small piece of marshmallow, what should I do?

If your cat ingested a small piece of marshmallow and shows no signs of distress, they will likely be fine. However, it is best to monitor them for any signs of digestive upset or unusual behavior. If you notice any concerning symptoms, contact your veterinarian for advice.

2. Can I give my cat marshmallows made with natural ingredients?

While marshmallows made with natural ingredients may contain less harmful additives, they are still not a suitable treat for cats due to their high sugar content. Cats should stick to a balanced diet of cat-specific treats that meet their nutritional needs.

3. Why is xylitol harmful to cats and dogs?

Xylitol is harmful to cats and dogs because it can lead to a rapid drop in their blood sugar levels, causing hypoglycemia. Hypoglycemia can lead to weakness, lethargy, seizures, and even death if left untreated.

4. Are there any sweet treats that are safe for cats?

There are cat-specific treats available that are formulated to meet cats’ dietary needs and are safe for occasional indulgence. Look for treats that are made with high-quality ingredients and approved for feline consumption.

5. Can I give my cat other human foods as treats?

While some human foods may be safe in small amounts, it is best to avoid feeding human treats to cats. Cats have unique dietary requirements, and their digestive systems are not optimized for processing many human foods. Stick to cat-specific treats that are safe and beneficial for their health.


While marshmallows are not toxic to cats, they are not a suitable treat for feline companions. Cats have specific dietary needs as obligate carnivores, and sugary treats like marshmallows can lead to potential health issues. It is essential to prioritize your cat’s health and avoid feeding them foods that are not designed for their nutritional requirements. Instead, opt for cat-specific treats that provide the right balance of nutrients and are safe for occasional indulgence. If you have any concerns about your cat’s diet or health, consult with your veterinarian for personalized advice.
