Can Cats Eat Lemons?
No. Lemons are not safe for cats because citrus plants contain essential oils and psoralens that can be toxic, and cats are especially sensitive to essential oils.
Lemons are not safe for cats
Lemons and other citrus plants are considered toxic to cats. The peel, plant material, and essential oils are the biggest concern, but even the fruit and juice can cause drooling, vomiting, diarrhea, and irritation.

Why Lemons Are Dangerous for Cats
Lemons are a poor choice for cats and can be toxic. ASPCA lists lemon as toxic to cats due to essential oils and psoralens. Cats are more sensitive than dogs to essential oils because they have limited liver glucuronidation, so citrus oils are more concerning in cats than in dogs. The highest-risk parts are the peel, leaves, stems, and concentrated oils; the sour fruit and juice are still irritating and can upset the stomach.
- Do not intentionally feed lemon to your cat
- Peel, rind, leaves, stems, and lemon essential oil are more dangerous than a tiny lick of flesh
- Cats are especially sensitive to citrus essential oils and liquid potpourri
- Possible signs include drooling, vomiting, diarrhea, depression, mouth irritation, and dermatitis
- If your cat ate lemon peel or was exposed to lemon oil, call your vet right away
