Are radishes like cherry radishes safe for cats to nibble on if they show interest?

Yes, a thin slice of a mild radish like a cherry radish is generally safe for a cat to try. The main risk comes from the spicy compounds in some radishes, which can irritate a cat's sensitive stomach and cause vomiting or discomfort. Offer only a tiny, plain piece and monitor your cat closely for any adverse reactions. If your cat eats a larger amount or a particularly spicy variety, watch for signs of stomach upset and contact your vet if you're concerned.
