Can cats eat Potato?

Caution

Caution. Cooked plain potato in small amounts is low-risk. Raw potato, potato peels, and green-tinged potatoes contain solanine (toxic) and should never be fed. Chips and crisps are also problematic due to salt and fat.

If your cat has eaten potato

  1. For cooked plain potato: monitor for GI upset.
  2. For raw, sprouted, or green potato: call your vet.
  3. For chips or crisps: consider salt and flavouring content — call vet if flavoured.

What's the full picture?

Solanine is the toxin in the nightshade family (potato, tomato, aubergine). It's highest in green potatoes, sprouted potatoes, and potato peels. Cooking reduces but doesn't eliminate it.

Small amounts of cooked white potato flesh aren't toxic but have no nutritional value for cats. Sweet potato is a different species and is lower-risk but still unnecessary.

Chips (UK chips = US fries) and crisps add salt, fat, and often onion/garlic seasoning — avoid.

Symptoms to watch for

0–24 hours
Vomiting, diarrhoea (raw/green potato). Neurological signs with larger ingestions.

About this guidance

Every entry on this site is compiled from published UK veterinary toxicology sources — International Cat Care, Veterinary Poisons Information Service (VPIS) references, RCVS-registered practice materials, and peer-reviewed feline medicine literature. Where the evidence is mixed, we err on the cautious side because cats are unusually sensitive to many common substances that are harmless to humans and even to dogs.

This is general information written for UK cat owners. It is not personalised veterinary advice for your specific cat, their age, weight, medical history, or the exact exposure you're dealing with. If your cat has eaten something or is unwell, call your vet first. The Animal PoisonLine on 01202 509000 is available 24/7 for a small fee and can tell you whether an emergency visit is needed.

Entries are reviewed and updated as new research emerges. Spotted an error? Let us know — corrections are investigated and applied within 24 hours. For more context on how we work, see about and our full disclaimer.
