The first building block in preventing disease is proper nutrition. A vast majority of pets eat what would be considered a complete and balanced diet, but they are not getting their individual needs met nutritionally. Paying close attention to the ingredients in commercially produced food and supplementing your pets diet with vitamins and minerals is a good start. Statements like "complete and balanced for nutritional needs" should be taken with scrutiny. There may be a proper amount of vitamins and minerals in the can, but your pet may not be absorbing these nutrients for a variety of reasons.
It’s best to create a diet for your pet with natural foods designed with his or her needs in mind. These natural foods should be palatable, preservative free, practical and cost-effective, as well as environmentally sound.
