When people start to make healthy choices for themselves, thinking about their pets is a natural extension; after all, most pets are considered part of the family. Pet products now make up a multi-billion dollar segment of the natural products industry, with pet supplements alone accounting for $1.4 billion in 2008 (a 7.4 percent growth over the previous year—faster than the sales of human supplements). According to a 2008 study, dogs’ and cats’ toxic loads from food and the environment rival and often exceed those of their human companions, so there’s ample incentive to provide consumers with research-backed, natural care options to maintain and extend their pets’ health and well-being.
