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

Rex Begonia and Iron Cross Begonia are frequently compared by houseplant enthusiasts because both belong to the same Begonia genus. If you are choosing between these two varieties for a home with pets, it is important to know that both plants are considered potentially toxic to cats and dogs. Each contains soluble calcium oxalates, which can cause immediate irritation and discomfort if ingested. While the specific foliage patterns and textures differ significantly between these two popular ornamental choices, the safety risks for your furry companions remain consistent across both species. Always monitor your pets closely around these plants and consult your veterinarian if you suspect any ingestion has occurred.
