Pulsar offers a selection of truly affordable single protein, grain free formulas with an emphasis on 'pulses' such as red lentils and peas which are highly digestible, low glycemic and antioxidant rich carbohydrates. Grain free formulas have been a significant and positive movement in pet foods over the last decade. Unfortunately, 'grain free' is now commonly used as a marketing ploy to portray 'better quality' and therefore higher prices. Don't be fooled. Horizon starts with an emphasis on animal protein. Steroid free and growth hormone free chicken, turkey and wild caught salmon are the cornerstone proteins in Pulsar. The nutritional and energy benefits of pulses (legumes) are unquestioned. High dietary fiber, exceptionally low glycemic indices and packed with antioxidants. This is what grain free aspires to be. They use red lentils and peas which we source right where they operate - direct from growers. No low cost potato or tapioca sourced through global agents. That's for pet foods looking to claim 'grain free' but using carbohydrate alternatives that don't measure up and simply don't justify the price tag.
