So, what's the big deal about food? Why does it have such a huge influence on a body's health? Well, simply put, food is body-fuel. It nourishes each and every cell in the body and creates the energy necessary for life to happen. It's an overly simplified analogy, but food is to living beings like gas is to cars.

If you put the wrong type of gas in a car, it won't run well. But if you put in the correct fuel for that car, it runs better.Read MoreNext to air, food is the substance our cats take into their bodies most often. How long they live, their quality of life, the health of their immune system, and their behavior all depend greatly on the food they eat. Food is the foundation for health. It's really no different than what we hear today about human health. The experts keep telling us that if we wish to live a long healthy life, we need to eat more fresh real food and cut out the processed food products. It seems that every day brings new research to support this advice. As both humans and felines have strayed from eating fresh foods, both our species have suffered a huge increase in disease; obesity, diabetes, allergies, cancer, behavior problems, and more.

These days, there are so many bottles of nutritional "supplements" on the market and so many processed fake foods that perhaps we've forgotten that real fresh food is the original and best source of all those vitamins, minerals, enzymes, antioxidants, and other important nutrients necessary for good health. Even in our modern day, malnutrition is still a very real issue for cats (and humans). Malnutrition puts a great deal of stress on the body and lowers the energy needed to maintain good health. Malnutrition may be caused by lack of food, poor quality food, or food cats cannot utilize if it's not appropriate for their species Felis domesticus.
