Rex Begonia vs. Elephant-Ear Begonia: which is safe for cats and dogs?

Rex Begonia and Elephant-Ear Begonia are frequently compared because both belong to the Begonia genus and share similar care requirements as popular ornamental houseplants. If you are choosing between these two for your home, it is important to know that both plants are considered potentially toxic to cats and dogs. Each contains soluble calcium oxalates, which cause immediate irritation to the mouth, tongue, and throat upon ingestion.
