Philodendron vs. Heartleaf Philodendron: which is safe for cats and dogs?

Philodendron and Heartleaf Philodendron are frequently compared because both plants share the common-name alias Sweetheart Plant, leading to confusion for pet owners looking to green their homes. It is important to know that both of these plants are potentially toxic to cats and dogs. They contain insoluble calcium oxalate crystals, which cause immediate discomfort and irritation upon contact with the mouth and digestive tract. While the severity of the reaction is generally localized to the gastrointestinal system, ingestion should always be taken seriously. Understanding the risks associated with these popular tropical varieties will help you keep your pets safe and comfortable in your living space.
