Is rieger begonia safe for cats and dogs?
Toxic — the ASPCA lists rieger begonia 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. The ASPCA lists Begonia (Begonia spp., family Begoniaceae, which includes B. × hiemalis) as toxic to cats, dogs, and horses. The toxic principle is soluble calcium oxalates, and the most toxic part is underground (tubers, rhizomes, and roots). Ingestion can cause vomiting and salivation in cats and dogs, and kidney failure in grazing animals; keep it away from pets and contact your vet if eaten.
