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

Wax Begonia and Rex Begonia are frequently compared because both belong to the Begonia genus and share similar care requirements as popular indoor plants. If you are a pet owner, it is important to know that both of these plants are considered potentially toxic to cats and dogs. Each variety contains soluble calcium oxalates, which cause immediate irritation and discomfort if ingested. While neither plant is typically considered fatal, the presence of these crystals means that both the Wax Begonia and the Rex Begonia can cause significant distress to your pets. Understanding their shared risks will help you keep your home environment safe for your animals.
