Can Cats Eat Marshmallows?
Not recommended. Plain marshmallows are not a good treat for cats, and sugar-free versions can contain ingredients that should still be avoided even though xylitol does not cause the same life-threatening toxicity in cats that it does in dogs.
Usually low-toxicity, but still not a safe cat treat
Plain marshmallows are mostly sugar and offer no nutritional benefit for cats. The biggest concerns are stomach upset, choking, wrapper ingestion, and hidden ingredients like chocolate or other sweeteners in flavored or sugar-free products.
How urgent is this?
Go to the ER now
- ● Your cat is choking, struggling to breathe, collapsing, or having seizures
- ● Your cat ate chocolate-covered marshmallows or another marshmallow product with a known toxic ingredient
- ● Your cat swallowed wrappers, skewers, or a large sticky mass and now has repeated vomiting, abdominal pain, or trouble passing stool
See a vet within 24 hours
- ● Your cat ate a large amount of marshmallows and is vomiting, drooling, lethargic, or has diarrhea
- ● You are unsure what ingredients were in the marshmallows, especially sugar-free or flavored products
- ● Your cat has diabetes, obesity, pancreatitis, or another medical condition and ate marshmallows
Watch at home, call if it worsens
- ● Your cat licked or ate a small piece of a plain marshmallow and is acting normal
- ● Mild, short-lived stomach upset after a tiny amount
Why Marshmallows Aren't a Good Choice for Cats
Cats are obligate carnivores, so marshmallows are nutritionally inappropriate and should not be offered as treats. Plain marshmallows are mostly sugar and syrup, which can upset the stomach and add unnecessary calories, while sticky texture and wrappers can create choking or gastrointestinal obstruction risks.
- Plain marshmallows are not toxic to most cats, but they are high in sugar and offer no meaningful nutrition
- Cats should get no more than about 10% of daily calories from treats, and meat-based treats are a better option
- Sugar-free marshmallows should still be avoided; xylitol does not cause the same severe hypoglycemia and liver injury in cats as in dogs, but these products are not appropriate for cats
- Chocolate, candy coatings, spices, or other added ingredients may make a marshmallow product more dangerous
- If your cat eats marshmallows, remove access, check the ingredient list, monitor for vomiting or diarrhea, and call your vet if you are unsure
