New petfood designed to change with the seasons

A 2006 study conducted by the US National Research Council reported that the metabolic energy requirements of pets change with the weather. In short, pets need more energy in the winter and less in the summer. To that end, Seasons has come up with two blends of petfood. One is formulated to complement warm-weather needs, the other to do the same for cool-weather needs. According to the company, both blends "deliver the proper amount of protein, fat and climate-specific nutrients when the pet needs it most." The food is offered in three flavor formulas: chicken meal and brown rice, lamb meal and brown rice and a multi-protein formula.
