Interpretation: Ground Yellow Corn is the entire ear of corn, including the cob but without the husk, ground up. Corn is a leading source of allergies in pets. And more importantly, why would corn be the first ingredient in any cat food? Cats are obligate carnivores. In addition, corn is very difficult to digest and utilize. The official definition of Poultry By-Product Meal is as follows: Consists of the ground, rendered, clean parts of the carcass of slaughtered poultry, such as necks, feet, undeveloped eggs and intestines, exclusive of feathers, except in such amounts as might occur unavoidable in good processing practice. Note that this is an inconsistent ingredient, because of the multiple organs used and their constantly changing proportions. They are cheaper and less digestible than chicken or chicken meal. It is also better to see a specific protein named, such as chicken, rather than the generic poultry. Anything called a by-product means it is not deemed fit for human consumption, and may even contain diseased or chemically tainted tissue. Animal Fat is obtained from the tissues of mammals and/or poultry in the commercial process of rendering. This can come from any type of animal in a rendering plant, including road-kill, chemically tainted, diseased or euthanized animals. Clearly, animals fit for human consumption are not sent to rendering plants. Corn Gluten Meal is the dried residue from corn after the removal of the larger part of the starch and germ, and the separation of the bran. Not only is this another corn fragment, it is added to pet food to slow down the transition of rancid animal fats (think toxic waste!), which then holds waste in, stressing the kidneys and liver. Brewers Rice is officially defined as the dried extracted residue of rice resulting from the manufacture of wort (liquid portion of malted grain) or beer. Brewers Rice is a low-quality rice fragment that is missing many of the nutrients found in the whole rice kernels. Soybean Meal is obtained by grinding the flakes that remain after removal of most of the oil from soybeans. Not only is it a fragment, it is a poor quality protein filler used because it is so cheap. It is also believed that soybeans are a leading cause of allergies in pets. Animal Digest comes from the chemical or enzymatic treatment of clean and undecomposed animal tissue (in a rendering plant). It says it cannot contain hair, horns, teeth, hooves or feathers, except in trace amounts. Just as in Animal Fat (above), it can come from any type of animal, and from the same questionable or even contaminated sources. Calcium Carbonate is a source of calcium, but that is what raw bones are for! Calcium Carbonate is also an ingredient in many antacids. Salt is not something we need to be adding to our pets food! Potassium Chloride is used as a salt substitute and to replenish electrolytes, but it is also used in fertilizer and in massive doses for lethal injections. Vitamin E Supplement sounds like a great idea, but (just as with all the un-bolded mineral supplements listed) why is it needed if they are using good ingredients, and how much of the nutrition survives the cooking process? Added Color. What needs to be said? These are chemical additives, which some fear are carcinogenic, simply to make the food pretty colors. Do cats care what color their food is???
