Cooked only—never raw or green

Can cats eat potatoes?

A small bite of plain, thoroughly cooked potato can be okay for a cat, but raw and green potatoes are unsafe. They contain solanine, so this is one food where preparation changes the answer completely.

Alternatives to potatoes for cats

If you want a small, gentle-textured reward, a cat treat provides a safer shortcut than navigating the raw-versus-cooked potato distinction.

How much is okay?

Only offer a tiny piece of plain fully cooked potato. Never feed raw, green, sprouted, or seasoned potato.

Kitten / small adult
1/2 teaspoon mashed or a tiny cube
Fully cooked and plain only.
Typical adult
1 teaspoon
An occasional extra, not a meal.
Large / big appetite
Up to 2 teaspoons
Do not displace meat-based food.

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

How to prepare them

  • Peel and cook potato thoroughly until soft using water only.
  • Discard every raw, green, sprouted, or damaged piece.
  • Serve a tiny plain cube or plain mash after cooling.
  • Never share fries, chips, roasted potatoes, mashed potatoes with dairy, or seasoned dishes.
  • Keep raw potatoes and potato plants out of reach.

Risks & exceptions

  • Raw and green potatoes contain solanine, which is toxic to cats.
  • Potato skins, sprouts, and green portions are especially concerning.
  • Fries, chips, and buttery mash add salt, fat, and seasonings.
  • Potato is starchy and should not replace complete feline nutrition.

Never feed raw, green, sprouted, or potato-plant material. Cook plain potato thoroughly and keep portions very small.

If they ate too many

Plain cooked potato is usually uneventful in a tiny serving. Raw or green potato exposure needs prompt veterinary advice.

  • Gas
  • Soft stool
  • One episode of vomiting
  • Reduced interest in regular food

Call your vet / pet poison line if:

  • Any raw, green, or sprouted potato ingestion
  • Chewing potato leaves or stems
  • Weakness, confusion, or dilated pupils
  • Repeated vomiting or trouble breathing
