Is Manchurian Walnut toxic to cats?

Juglans mandshurica

Toxic to cats

Yes — manchurian walnut is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Juglans is not individually listed by the ASPCA, but Manchurian walnut shares the genus's hazards: moldy nuts and husks can carry tremorgenic mycotoxins (penitrem A) causing tremors and seizures in dogs, and the fatty kernels risk GI upset or pancreatitis. Juglone in hulls and roots is toxic to horses. Keep fallen nuts and husks away from pets and livestock; consult a vet on any ingestion.
