Is holly-leaved naiad safe for cats and dogs?
Mildly. The ASPCA flags holly-leaved naiad 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. Najas marina is not listed by the ASPCA. No specific pet-toxicity data exists for this species or genus; classified mildly-toxic as a precaution. The spiny leaf teeth may cause minor oral irritation in pets that chew the plant.
