A recent investigation by the Clean Label Project tested 100 cat food products from 62 brands and found traces of heavy metals, pesticides, and plastic-related chemicals. Substances detected included lead, arsenic, cadmium, mercury, and glyphosate, with levels varying between products. While detecting these substances does not necessarily mean the food is harmful, the findings raise questions about long-term exposure. Researchers highlight the need for continued testing and greater transparency in pet food safety.
