Cats should not eat marshmallows. While marshmallows are not toxic to cats, they contain high amounts of sugar and sodium, which provide no nutritional benefit and can contribute to health problems like obesity and digestive issues. Additionally, marshmallows’ sticky and gooey texture poses a choking hazard for cats. Some marshmallow varieties may also contain xylitol, a sweetener highly toxic to cats. It is best to avoid sharing marshmallows with cats and instead offer treats specifically made for feline nutrition.
