Is giant fishtail palm safe for cats and dogs?
Mildly. The ASPCA flags giant fishtail palm 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. The fruit mesocarp of Caryota maxima contains calcium oxalate raphide crystals, which cause intense oral burning, drooling, and vomiting in pets and people if ingested. Handle fruits with gloves. Caryota is not individually listed on the ASPCA database; however, the calcium oxalate hazard from the fruits is well documented in veterinary sources. Leafy parts are not reported as toxic.
