What makes it harmful
psoralens (phototoxic) and the essential oils limonene and linalool, concentrated in the peel and plant parts
What to do if eaten
If the peel or a lot of flesh is eaten, watch for vomiting, drooling, or skin irritation and contact a vet.
How to serve safely
A tiny taste of the flesh is usually fine. But the peel, pith, leaves, and concentrated citrus oils can cause vomiting, diarrhea, and even phototoxic dermatitis (ASPCA lists lemon as toxic). Skip citrus as a treat — there are better options.
