Safety Overview
Cooked potatoes are safe for cats in moderation, but raw potatoes and potato plants contain solanine, a toxic compound that can cause serious illness. Green potatoes (exposed to light) have elevated solanine levels and should never be consumed. Potato plants, including leaves and stems, are also toxic. If you grow potatoes, ensure your cat cannot access the plants.
