Is tuberous begonia safe for cats and dogs?
No — tuberous 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. Begonia is ASPCA-listed as toxic to cats, dogs, and horses. The toxic principle is soluble calcium oxalates, most concentrated in the tuber. Signs of ingestion include oral burning and irritation, drooling, vomiting, and difficulty swallowing. The stored tubers are the most hazardous part, so keep them and the growing plants out of reach of pets and consult a vet if eaten.
