Dog food is food certainly formulated and intended for consumption by dogs and other related pets. Like all dogs have sharp, pointed teeth, and have short gastrointestinal tracts better suited for the consumption of meat than of vegetable substances. Regardless of this natural zoophagous design, dogs have still managed to make alterations over thousands of years to hold on the meat and non-meat fragment and thrive on a variety of foods, with studies suggesting dog's ability to digest carbohydrates easily may be a key difference between dogs and cats.
Cat food is food for consumption by cats. Cats have clear-cut requirements for their dietary nutrients. Few nutrients including many vitamins and amino acids are degraded by the temperature, pressure and chemical treatment used during construction and hence must be added. The amino acid for example taurine, which is found in meat and is degraded during processing, so synthetic taurine is normally added afterwards. Long-term taurine deficiency may result in retinal degeneration, loss of vision, and cardiac arrest. Contrary to popular belief, most cats dislike insects and probably eat them mistakenly which results in a bad stomach followed by vomiting.
