Ready-made dog and cat food is relatively cheap and convenient, and it wasn't until the 1930's that commercial pet foods were introduced in the US. Commercially prepared kibble has become the standard diet for pets, but it's a far cry from a dog or cat's natural diet. Our dogs and cats are descendents of wild animals who evolved over thousands of years to thrive on a specific diet.
Dogs have short intestinal tracts designed to quickly and efficiently digest meats, and cats are carnivores intended by nature to hunt small rodents and birds. Carbohydrates, in fact, are a cat's worst enemy; their digestive tract is simply not designed to absorb them.
Conventional pet food manufacturers may brag that their food are brimming with quality meats, vegetables and grains, but a close look at the ingredients used often tells a different story. These ingredients can include: beaks, feet, feathers, hooves, horns, entrails; "4D"-dead, dying, diseased or disabled animals; ground corn, gluten meal, and wheat impart no nutritional value for dogs and cats. They even present potential health hazards.
Switching from mass-produced commercial food to organic or all-natural foods is fundamental to avoiding common pet health problems, including allergies and cancer. Switching your four-legged companion to an organic diet will boost the animal's immune system and your pet may live longer.
Organic food is more expensive, but you end up with a healthy pet and, in the long run, lower vet bills.
