Is knap hill scarlet quince safe for cats and dogs?
Mildly. The ASPCA flags knap hill scarlet quince 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. Chaenomeles fruits contain cyanogenic compounds in the seeds, similar to other Rosaceae members. The fleshy fruit pulp is edible (often used in preserves) but raw seeds should not be consumed. ASPCA does not individually list Chaenomeles; caution advised around pets that may chew woody stems or seeds.
