Οποιος θελει ας ριξει μια ματια σε αυτο (η μελετη ειναι τεραστια κ δεν μπορω να την παραθεσω ολοκληρη αν και εχει ιδιαιτερο ενδιαφερον)...
Cats should live for 30 years - unless you don't feed them healthy food! The longest reported cat life span was 37 years. It's so sad and shameful that our beloved pets are dying far too soon. A primary cause of poor pet health and the much shorter life span of cats is poor nutrition! (This is also true for humans.)
The average cat or dog in the world rarely reaches even half of its potential life span. Today the average life span of a cat is only 12 years (some studies say 14). Yet some cat breeders who are serious about feeding their cats the healthiest foods raise cats that live to be 20 years old or more.
Today, the average cat is lucky to live to less than half of his potential life expectancy - only 12-14 years. You may think that 12 years of life is "normal" for a cat - but it really isn't. It's abnormal for a well-fed cat to live for just 12 years. It's only "normal" for a cat that is NOT well fed, a cat which isn't getting all the nutrition it needs to live a healthy and long life.
Cats are obligate carnivores that need to eat real meat and fowl and fish, such as the kind that comes from healthy cows, pigs, sheep, goats, chickens, turkeys, and fish - not diseased dead animal carcasses, chicken heads and feet, wheat products, corn products, soy products, byproducts, bone meals, feathers and fillers.Cats are "obligated" to eat mostly meat. If they don't live up to this obligation, they will not live very long. They might make it to 11 or 14 years, when they really should be living to the ripe old age of 30 years. You say you've never met a cat over 20 years old? Or 15? That's because ever since someone started selling commercial cat food, cats have been getting less and less high-quality meat - and getting less and less years of life. Something is stealing those precious pet years, and the prime suspect is poor quality pet foods.
All you need to feed your carnivorous cat is a lot of meat protein, some animal fat, and a bit of carbohydrates that are easiest for it to digest. That would NOT be wheat, corn, or soy. Whole brown rice is a grain from which cats are able to absorb nearly all the nutrients. White rice is not, because most of the nutrients were stripped away when the outer hull was removed from the brown rice. A continual diet of white rice could cause a cat or dog (or human) to develop diabetes.Cats do not need many carbohydrates in their diet. Yet far too much is added to many or most commercial cat foods. So carbs could be considered as generally useless "filler" in cat foods, and you may not wish to pay good money for cat foods full of things your cat does not really need. They fill the can or bag with useless fillers and leave little room for the meat the cat really needs.Remember, cats don't really need much carbohydrate, so for optimal health give them cat foods with more meat, and less grains or starchy vegetables.
In many brand cat and dog foods, two out of three of the top-listed ingredients are usually some form of grain or cereal, especially in the dry pet foods. And they will likely be grains that were graded as unfit for human consumption. Again, the more grains and cereals in the cat food, the less meat your cat will eat. Remember, cats are meat eaters. Wild cats do not eat wheat or corn....
Some things on cat food ingredient lists you may wish to AVOID are:
Words such as...
(1) "byproducts" or by-products (waste products processed in rendering vats, including 4D animals - "dead, dying, disabled or diseased"),
(2) "animal digest" (rendered waste products which undergo further processing then are dried),
(3) "meat and bone meal" and/or "bone meal" (not nutritious, produced from rendered waste products),
(4) most other items which include the words "digest" or "meal" (such as "animal digest" or "animal meal") if they do NOT include the specific name of the source of the material (such as "beef meal" or "chicken meal" or "catfish meal"),
(5) "corn meal" (not nutritious for cats, and may cause allergies - and likely includes corncobs),
(6) "gluten" such as "wheat gluten" or "rice gluten" (in the pet food recall, toxic melamine was found in over 100 brands of dog and cat foods which contained these two types of "gluten" and also "rice concentrate". These are added to increase the "protein" content on the nutrition label, but are lower-quality vegetable proteins which help disguise the lack of animal protein, which is what cats need. Wheat gluten is also a leading cause of food allergies.),
(7) added sugars and salts (unnecessary sugars will be listed as corn/ or wheat/ or rice gluten meal; beet pulp; or corn syrup),
(8) chemical preservatives, including BHA, BHT, Ethoxyquin, propyl gallate (see Unhealthy Preservatives),
(9) food colorings or dyes (they are added only to deceive you into believing a cheap pet food loaded with byproducts and cereals looks like real red meat),
(10) cat foods which do NOT have an expiry date or "Best Before" date printed on the package......
