Is sharp-lobed begonia safe for cats and dogs?
No — sharp-lobed begonia 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. The ASPCA lists Begonia (Begonia spp.) as toxic to cats, dogs, and horses. The toxic principle is soluble calcium oxalates; the highest concentrations are in the underground roots and rhizomes. Ingestion causes oral irritation, intense burning and tingling of the mouth and tongue, drooling, and vomiting in cats and dogs, and can cause kidney failure in grazing animals. Keep out of reach of pets.
