Dry Pet Food IS Hazardous to Your Pet's Health
Don't take our word as gospel on the dangers and perils of dry processed foods for your pets. Below are quotes taken from reputable websites and trusted pet resources you should read. The information speaks for itself, and the sources are as trusted and credible you can find anywhere.

Dry food contains 6 to 10 percent moisture. Depending on the specific formulation, meats or meat byproducts, poultry or poultry byproducts, grain, grain byproducts, fish meal, fiber sources, milk products, and vitamin and mineral supplements are combined, extruded, and dried into bitesized pieces. The pieces are then covered with flavor enhancers, such as animal fat, which give them increased palatability. The primary advantages of dry cat food are lower cost and convenience in allowing "free choice" feeding. However, dry food may be less palatable to a cat, and, depending on the types and quality of the ingredients, may also be less digestible than moist food. If you do use dry food, it is important to store unused portions in a cool, dry location, and not to use the food after its expiration date (which is printed on the container). Often owners buy large amounts of dry food that can sometimes last for 3 to 6 months; therefore, checking the expiration date before feeding it to your cat is very important. Lengthy storage decreases the activity and potency of many vitamins and increases the likelihood that fats have become rancid. Storing dry cat food in an airtight container can help prevent nutrient deterioration and help maintain palatability.
Bio-Inappropriate: The Dangers of Dry Food
It is very important to remove dry food from your cat's diet. This one change alone is a big step forward in improving your cat's health. Dry food, be it premium, prescription or "natural," harms your cat's health. It consists mostly of starch and carbohydrates — it must be, as it can't be manufactured and extruded otherwise. It is not the vital protein that your cat, an obligate carnivore, requires and is detrimental to health.¹
The problems with dry food are:
It is far too low moisture content,
It is far too high in carbohydrates,
It contains protein from plant rather than animal sources.
Additional Problems With Dry Food
Dry food as it is initially manufactured would be of no interest to a cat. It must be sprayed with flavorings and their accompanying odors to interest the cat in eating it.¹⁰ An entire industry has arisen to manufacture such sprays for this biologically inappropriate food product.
Wet Food Diet: Is it Better For Your Cat?
"An exclusive dry food diet just won't do it either, as your cat doesn't get a sufficient amount of water from the kibble. ... Well, short of using a syringe to force feed your cat water, you might want to think about switching your cat to a wet food diet, or at least a partial wet food diet."
10 Reasons Why Dry Food Is Bad for Cats & Dogs
As a holistic veterinarian and animal advocate with more than 20 years of experience and thousands of hours of research under my belt, I’ve concluded that dry food is not a fit diet for our cats and dogs–carnivores who need a meat-based diet.
To make dry food, whatever rendered high-protein meal is being used is mixed into a sticky, starchy dough that can be pressed through an extruder, which forms the kibble. The dough is forced by giant screws through a barrel and ultimately into tiny tubes that end in a shape, much like a cake decorator. The heat and pressure in the extruder are tremendous. ... Not only are cooked proteins less digestible, but they become distorted, or “denatured,” by heating. These abnormal proteins may be a factor in the development of food allergies, as the immune system reacts to these unfamiliar and unnatural shapes. ...The normal food enzymes that would help digest the food are destroyed by the heat processing that dry food undergoes. This forces the pancreas to make up for those lost enzymes. Over time, the pancreas can become stressed and enlarged, and even get pushed into life-threatening pancreatitis.

Dry food is very heavily processed which includes being subjected to high temperatures for a long time resulting in alteration and destruction of nutrients. ... There is no doubt that dry food is responsible for far more intestinal problems, and other diseases, than most veterinarians and cat owners realize.
Common medical problems associated with dry food
Cystitis/Urethral blockage/Urinary tract infection/Crystals
Inflammatory Bowel Disease
Hepatic Lipidosis (fatty liver disease)
Avoid carbohydrate-based foods that can set your cat up for dental problems
"A small test with dogs conducted in Australia showed how quickly dry foods can affect the teeth.² Four dogs, who were all raw meaty bone eaters, were fed only dry kibble for 17 days. At the end of the experiment, the dogs had developed stinky breath and yellow teeth. Some of them lost weight. All of them had behavioral changes, itchy skin, bad breath and intestinal disorders including larger volume of stools, offensive smell and runniness. Even though this test was with dogs, not cats, the effect is the same for carnivores that evolved to eat a prey-based diet.
