When choosing food, the price on the bag, while important, is usually not the best consideration. A low price may indicate cheap ingredients, or ingredients that change as manufacturer costs fluctuate.
In addition, many lower-priced products have higher daily portions to provide the same amount of nutrition found in a high-quality diet. To get a better idea of cost, it is the cost per feeding, not the total cost, that counts.
To figure cost per feeding, divide the total cost by the number of days the product lasts. For example, a 20-lb bag of food that costs $18.99 and lasts 30 days is $0.63 per day. A 20-lb bag that costs $15.99 and lasts 20 days costs $0.80 per day. When compared closely, high-quality pet foods are quite favorable to other brands.
