Sweet potato, and other veggies or starchy food, should not form a major part of your cat’s food, and should only be fed on an occasional basis. Sweet potatoes are known for their high level of carbohydrates, which can cause obesity in our cats, so potato treats should not be given often.

Are Sweet Potatoes Used in Commercial Cat Food?

Yes, some commercial diets use sweet potato as an ingredient. Commercial cat foods are usually animal protein-based, which is what cats’ digestive systems are adapted to, but use safe vegetables, potatoes, and legumes as added fillers. Sweet potato is often used as a filler which also functions as a digestive aid.

The ASPCA lists the sweet potato as being non-toxic to cats, including sweet potato vines, shoots, and stems. However, there are a few things to watch out for.


Too much sweet potato can cause an upset stomach, and the high level of carbohydrates can cause weight gain and obesity if given too often – just as if we ate too many potato chips or French fries.

Raw Sweet Potatoes

Uncooked potatoes can cause digestive issues and a really upset stomach, so should be avoided. Cooked potatoes are more suitable if you want to feed them as a cat food.


Sweet potatoes are safe, but you must still always check the recipe, as some of the commonly added seasonings can be dangerous.

  • Marshmallows – the high sugar content is not recommended for cats.
  • Onions and garlic – these are both toxic to cats and should be avoided in any amount.
  • Salt – too much salt causes excessive thirst and can cause imbalances in sodium and potassium levels leading to kidney problems. Canned sweet potatoes are often very high in salt and should not be given to cats.
  • Butter – this is a common ingredient in potato treats but high in fat which can lead to weight gain. Many cats are also intolerant to dairy.

This tasty veggie is safe for cats, if fed in small amounts and kept plain. Steamed sweet potatoes or baked sweet potatoes are ideal, as is plain mashed sweet potato.
