US retail sales of natural pet products exceeded $7 bn and achieved a 15 per cent compound annual growth rate over the 2010-2014 period, according to the market survey company Packaged Facts. The company believes that this trend is benefiting the speciality trade above all, while the mass-market dog and cat food categories are flat at best, and mass-market dry pet foods in particular are posting incremental declines in dollar as well as volume sales.
