Is plum 'stanley' safe for cats and dogs?
Toxic — the ASPCA lists plum 'stanley' as a clear no for cats and dogs. The painful part for the pet is usually quick and intense; the right move is to keep it out of any room a pet roams unsupervised. 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. Plum (Prunus) is ASPCA-listed as toxic to cats, dogs and horses. Stems, leaves and the stones contain cyanogenic glycosides that release cyanide, most concentrated in wilting leaves and the kernel; the ripe flesh itself is not the toxic part. Signs include brick-red mucous membranes, dilated pupils, panting, breathing difficulty and shock. Prevent pets from chewing prunings or fallen stones.
