EVO cat food is a grain-free, meat-based pet food from Natura Pet Products (owned by Mars Petcare). EVO is marketed as being a good supplement or alternative to raw food or homemade cat food diets.
Most dry cat foods are high in carbohydrate, and often contain a large percentage of processed grain. Grains are a relatively cheap and abundant source of filler for pet food.
EVO, however, is designed to deliver nutrition to your cat the way nature intended a carnivore to eat. High protein, low carbohydrate, and in this case, no grain.
Many cat health experts are concerned that consumption of excessive amounts of grains are unhealthy for cats (more about grain free cat food). Also, a high carbohydrate diet may be partly responsible for the number of cases of diabetes in cats. Feline obesity runs rampant, and is blamed mainly on diet.
In contrast, EVO boasts the highest protein content of any meat-based dry pet food on the market and "uses whole, fresh meat sources such as turkey, chicken and herring meal."
As of this writing, EVO cat food offers several products, both dry and canned, and either uses AAFCO (Association of American Feed Control Officials) Cat Food Nutrient Profiles or feeding tests.
Many cat owners have turned to raw food diets, or making homemade cat food recipes where meals are cooked much as you would cook a meal for a person.
EVO cat food is aimed at cat owners who might choose to feed a raw food diet (or make their own cooked meals), but offers the convenience of a packaged commercial dry food. Those who make their own cat food but can't always find the time to prepare it might find EVO a good fill-in product, or as a supplement to add variety.
Natura Pet Products was founded in 1989 by John and Ann Rademakers and Peter Atkins in Santa Clara, California. Their intention was to formulate a healthy pet food ("the healthiest pet food in the world"), made from whole, natural foods, with no artificial preservatives or chemical additives. The company emphasizes high quality control.
Along with numerous other smaller pet product companies, they have since been taken over by Mars Petcare, and some of their products have been discontinued by that pet food giant.
