Is iron cross begonia safe for cats and dogs?
Toxic — the ASPCA lists iron cross 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) as toxic to cats, dogs and horses. The toxic principle is soluble calcium oxalates, which cause vomiting and salivation in cats and dogs and can cause kidney failure in grazing animals; the most toxic part is underground (the rhizome/roots). The sap can also cause skin irritation in people. Keep it away from pets and children, and wear gloves when handling.
