Can they eat it? / Lemons and limes
Can dogs and cats eat lemons and limes?
Not worth it: too acidic, and the peel and oils are irritating.
The flesh is not toxic to dogs but nobody enjoys it; the peel, seeds and essential oils can cause stomach upset and, in cats, worse. Lemon-scented cleaners and oils are a separate hazard.
Drooling, vomiting, diarrhea; cats: weakness, tremors with the oil.
Offer water, skip the next meal, and call your vet if vomiting or diarrhea lasts more than a day or your pet seems unwell.
Careful for dogs means: fine in a small amount, prepared as described, and not for every pet; the details say when to skip it. Toxic for cats means: do not give it; if they ate it, call your vet or a poison line.
