Can cats eat sweet potatoes?

Cats can have a tiny amount of plain cooked sweet potato, but it is a starchy plant extra rather than a feline diet staple. Buttered, candied, or marshmallow-topped versions are a skip.

Not medical advice — general pet-safety info only. Confirm with your vet before changing your cat’s diet.

How much is okay?

Use a small plain mashed bite only occasionally; keep a cat's regular diet meat-based and complete.

Kitten / small adult
¼ teaspoon
Keep it tiny and occasional.
Typical adult
½ teaspoon
Plain preparation only.
Large / big appetite
1 teaspoon
Still an extra, not a meal.

Rule of thumb: treats of all kinds should stay under ~10% of daily calories.

How to prepare them

  • Cook until soft and mash plain.
  • Skip butter, milk, brown sugar, marshmallows, and cinnamon.
  • Cool before serving.

Risks & exceptions

  • Extra starch can cause soft stool.
  • Holiday dishes are often sugary and fatty.
  • Sweet potato should not replace complete cat food.

Sweet potato is a tiny plain add-in, not a feline meal or dessert.

If they ate too many

If they ate more than intended, watch for stomach upset and changes in behavior.

  • Soft stool
  • Gas

Call your vet / pet poison line if:

  • Repeated vomiting
  • Candied or marshmallow-topped sweet potato eaten
