Is williams pear safe for cats and dogs?
No — williams pear 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. Pyrus (pear) is grounded by the ASPCA stance on rose-family fruit trees: the seeds, leaves and stems contain cyanogenic glycosides that release cyanide when chewed in quantity. The ripe flesh is harmless, but ingestion of seeds, wilting leaves or prunings can cause drooling, dilated pupils, breathing difficulty and, in severe cases, shock in cats, dogs and horses. Keep pets from chewing prunings and seeds.
