Is calamondin orange safe for cats and dogs?
No — calamondin orange is toxic to cats and dogs. Keep it well away from any pet that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. The ASPCA individually lists Calamondin Orange (Citrus mitis, a synonym of Citrus x microcarpa, family Rutaceae) as toxic to dogs, cats, and horses. The toxic principles are citrus essential oils (limonene, linalool) and psoralens, concentrated in the peel, leaves, and stems; ingestion causes vomiting, diarrhea, depression, and potential photosensitivity (dermatitis). The fruit flesh is lower-risk, but keep pets from chewing the plant and call your vet if it is eaten.
