A popular trend in the petfood industry is consumers' recent demands for natural and organic petfoods. In an article from thedailygreen.com, Doug Mazeffa, research director at Greenopia.com, offers tips to consumers on selecting a "green" petfood.

While many consumers believe that organic, "green" petfoods often cost more per ounce, Mazeffa says these petfoods also tend to have higher concentrations of nutrients, meaning pets may not need to be fed as large of a quantity of the food. Mazeffa recommends that consumers check ingredient labels of petfoods in supermarkets so as to avoid harmful food preservatives. He also advises pet owners to stay away from petfoods that have the ingredient "meat and bone meal" listed on the label, because he believes this is the lowest quality protein.

To ensure the petfood is organic, Mazeffa suggests looking for food that is marked as certified organic and meets US Department of Agriculture standards for being free of pesticides, hormones, antibiotics and artificial preservatives.
