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

Begonia and Rex Begonia are frequently compared because both belong to the same Begonia genus, leading many pet owners to wonder if their specific variety is safer than others. It is important to know that both plants are considered potentially toxic to both cats and dogs. Because they contain soluble calcium oxalates, ingestion of either plant can lead to immediate oral irritation and digestive distress. While the severity of the reaction can vary depending on the amount consumed and the specific part of the plant ingested, you should treat both varieties with the same level of caution to keep your household pets safe and comfortable.
