Can Cats Eat Potatoes?
Caution — a tiny piece of plain boiled potato is harmless to a cat but offers no nutrition. Raw and green potatoes are toxic to cats too because of solanine; fries and chips are off the table.

What to know
As an obligate carnivore, a cat has no need for starch; a small taste of plain boiled potato is harmless yet pointless. What matters is the risk side: raw, green, or sprouted potatoes and the plant's leaves can cause solanine poisoning in cats. Chips and fries are unsuitable due to fat, salt, and seasoning.
Watch for these signs
- Vomiting, diarrhea
- Lethargy
- Excessive drooling
If you notice any of these, contact a veterinarian without waiting.
Frequently asked questions
My cat ate some chips — how bad is it?
One or two small pieces usually pass, but the salt load is high for a cat's small body. If a lot was eaten or you see vomiting or lethargy, ask your veterinarian; keep chips out of reach.
I see potato starch in cat food — is that a problem?
No — potato ingredients in cat food are cooked and safe; they serve as binders and energy in the formula.
