Is sweet orange safe for cats and dogs?
Mildly. The ASPCA flags sweet orange as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. 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. Citrus sinensis (orange) is listed as toxic to dogs, cats, and horses by the ASPCA. Toxic principles are essential oils and psoralens found in the rind, leaves, and stems. Clinical signs include vomiting, diarrhoea, depression, and potential dermatitis. The fruit flesh in small amounts is unlikely to cause serious harm, but foliage and rind pose a real risk.
