While Whistle demonstrates some commitment to sustainability through their device recycling program and eco-friendly packaging initiatives, they lack transparency in their supply chain practices and manufacturing processes. Their parent company, Mars Petcare, has made broader sustainability commitments, but Whistle-specific environmental impact data is limited. The company could improve by providing clearer documentation of their labor practices and environmental policies.
