Is least yellow pond lily safe for cats and dogs?
Use caution. Least Yellow Pond Lily is on the mildly-toxic side of the ASPCA list. Most ingestions are short-lived but unpleasant for the pet; the cost-free fix is a placement they can't reach. 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. Nuphar species contain quinolizidine alkaloids including nupharine and thiobinupharidine, which are potentially toxic if consumed. The genus is not listed on the ASPCA non-toxic database; ingestion may cause vomiting, incoordination, or lethargy in cats and dogs. Keep pets away from plant material and pond areas where rhizomes may be accessible.
