Begonia vs. Iron Cross Begonia: which is safe for cats and dogs?

Begonia and Iron Cross Begonia are frequently compared because both belong to the Begonia genus and share similar structural characteristics. If you are deciding whether to bring these plants into your home, it is important to know that both are considered potentially toxic to cats and dogs. While they are not typically fatal, both varieties contain soluble calcium oxalates that cause immediate irritation to the mouth, tongue, and throat upon ingestion. Because the severity of the reaction can vary depending on the amount consumed and the specific part of the plant ingested, it is best to keep both out of reach of your pets.
