Cat Food
From LoveToKnow Cats
Proper nutrition is the foundation for good health. Choosing the right cat food can make the difference between a long, healthy life and a short lifetime of debilitating disease.
Nutritional Requirements
Cats have special nutritional requirements, which are very different from the needs of dogs and people. Domestication has changed the behavior and appearance of cats, but not their digestive systems. They still have exactly the same nutritional needs that they have in the wild, and their food must precisely meet these needs or disease and organ failure will quickly take over.
Obligate Carnivores
Cats are obligate carnivores, meaning that they must eat meat in order to survive. They are pure predators, and their diet in the home must mimic what they eat in the wild in order for them to be healthy. Good cat food must have the same nutrients in the same proportions as whole prey. Natural prey animals for cats are rodents, birds, insects, and sometimes amphibians. It's actually a myth that fish are standard fare for cats.
Carbohydrates and Vegetables
As cats evolved, their digestive systems adapted to accommodate the available food, therefore all food must be high in protein from good meat sources, not by-products. Their systems have very little use for plant matter and carbohydrates. Premium cat food does not contain grains and contains very little vegetable matter.
Vitamins, Minerals, and Amino Acids
Because the nutrients that cats need are already present in whole prey, their systems do not convert and produce necessary nutrients from their foods, but rely on the prey’s digestive system to do this for them. Many amino acids, vitamins and minerals necessary for life must be readily available in a commercial feline diet. Taurine, Arginine, Vitamin A, and magnesium are some examples of necessary additives, but there are many more.
Water
Natural prey is sixty-five to seventy-five percent water. Domesticated cats evolved from desert cats where little water is available, so their bodies are adapted to extracting water from prey as their primary source of hydration.
Dry food contains very little water, so cats who eat dry food must increase their water intake in order to avoid dehydration, although many cats will not drink enough water to compensate. Their systems were not designed for the need to drink large amounts of water and it does not come naturally to them. Canned food has a significantly higher moisture content, so a diet that consists primarily of canned food will help prevent dehydration.
Choosing The Best Cat Food
Choosing the best food can be challenging. It is ultimately a balancing act between the best nutrition available and what you can afford.
Canned and Dry Food
When selecting a commercial cat food, there are some basic rules to keep in mind.
- Always buy food with real, named meat sources such as chicken or beef, not “meat” or "meat by-products".
- Avoid foods with the preservatives ethoxyquin, butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), which are highly toxic. Tocopherol (vitamin E) and ascorbic acid (vitamin C) are safe preservatives.
- Cat food should have little or no grains and only a small amount of vegetables.
- Change brands and varieties of food from time to time to avoid a chronic nutritional deficiency, and to prevent the development of food allergies.
Raw Food
A raw diet made from human grade foods and supplements is much healthier than commercial cat food, but only those who truly understand the nutritional needs of cats should attempt a homemade diet for their cat. It is very easy to get the nutrients out of balance and seriously compromise your cat’s health. Prepared raw diets can be purchased for cats online.
Whole Prey
The best diet for cats consists of exactly what they would eat in the wild – whole prey. Some people purchase live mice for their cats to kill and eat, or buy frozen mice to feed to their cats. Other prey animals, such as birds and insects, should occasionally be included in a whole prey diet. This is by far the most nutritionally appropriate diet, but not realistic for most cat owners.

Hi Kestrel,
I appreciate you sharing your opinion, and I wanted to add one more bit of information. A cat's digestive system is designed to pull most of it's liquid content from the food it eats. Cats actually don't drink a lot of water from bowls, so feeding wet foods is actually a healthy alternative, and really isn't spoiling them. In fact, vets actually recommend that cats that get urine crystals should be fed wet foods to increase their fluid intake.

You make some excellent points. Our cats no longer live in the wild, so it can be difficult to feed them this way. There are a few people who are able to feed their cats a raw diet, however, cats need a lot of specific nutrients, so this should always be researched thoroughly and monitored by a veterinarian.
-- Contributed by: LoriSoarda natural diet is fine as long as the cat is free to work it out for itself. Once humans start interfering it gets more complicated sadly. Yes, a cat will eat animals in the wild, and get their vegetation from what the animal has eaten or other sources when they need it, but it is their choice when their bodies tell them they 'need' something else. Domesticated cats have outside influences that, however much you try not to, will change this.
Additionally you have the RSPB, mammals trust, wildlife organisations etc who influence 'tree huggers' and you end up with cat haters. A perfect world would be great but is it workable? Just because some of us know that the natural diet is the best, natural cats just can't exist any more without risks.
A lot of research goes into good quality pet foods that overcome the things that domestic cats have to cope with that they wouldn't have to in the wild. All the cats' owners have to do is try not to spoil them all the time with wet food + 'what they like'. I like chocolate but I can't eat it all the time.
