Is flowering cherry 'kanzan' safe for cats and dogs?
No — flowering cherry 'kanzan' is toxic to cats and dogs. Keep it well away from any pet that chews plants; reactions can be significant. 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. Flowering cherry (Prunus) is ASPCA-listed as toxic to cats, dogs and horses. The stems, leaves and seeds contain cyanogenic glycosides that release cyanide, with wilting foliage especially dangerous. Although ornamental and not grown for fruit, fallen leaves and prunings pose the same poisoning risk — brick-red gums, dilated pupils, panting, breathing difficulty and shock. Keep pets from chewing leaves and prunings.
