POTTENGERS CATS
www.naturallyhealthydogs.co.uk

In 1932, Dr. Francis Marion Pottenger Jr. began an experiment in
nutrition, supervised by Dr. Pottenger and Dr. Alvin Foord who
was the professor of Pathology at the University of Southern
Carolina and also worked in pathology at Huntingdon Memorial
Hospital,Passadena.
 
This experiment lasted 10yrs using 4 generations of cats.
 
This experiment met the most rigorous scientific standards that
existed at that time, and there exists no other experiment which is
similar in any medical literature to this day.
 
The study was carried out to determine the effects to health of cats
when they were fed a diet where the food was processed using
heat [as commercial petfood is today when it is rendered].
 
Dr. Pottenger was concerned that the cats kept in his lab had very
poor survival rates, and another lab donated some of their cats
which appeared to be thriving and this caused him a problem in
meeting the demand for food, as they were still rapidly
reproducing, [one of the areas where his own cats were in decline
and only producing kittens with malformed organs and deformed
skeletons] so the new cats ended up being fed a raw diet, unlike
his own which were fed what was believed to be an optimum diet
and consisted of raw milk, cod liver oil and cooked meat [liver,
tripe, brains, heart,sweetbreads, musclemeat].
 
To begin with Dr. Pottenger fed raw scraps from a local meat
packing plant [including internal organs, muscle and bone] to a
separate proportion of the new cats so he could watch and observe
any changes and differences. What he observed was that within
just a few months, these cats, fed the raw scraps,were healthier
than their counterparts, with higher post-op survival rates and
healthy' vigorous kittens.
 
This was an amazing contrast, which prompted the following
controlled experiment to scientifically verify and show how the
diet was affecting them and how nutrition affected their health.
 
The Experiment :
 
900 cats spread over 4 generations were in the experiment, and
these cats were split into 5 groups.
 
All groups were given the same basic diet which supplied the
minimal basic requirements, but the major portions of the diets
were different.
 
Two of the groups were fed whole foods of raw milk and meat.
 
The other three groups were given processed foods:pasteurized,
evaporated and condensed milk.
 
*All 4 generations of the raw meat and raw milk groups remained
healthy throughout their normal lifespans.
 
*The 1st generation of all three processed food groups developed
diseases and illnesses near the end of their lives.
 
*The 2nd generation of all three processed food groups developed
diseases and illnesses in the middle of their lives.
 
*The 3rd generation of all three processed food groups developed
diseases and illnesses in the beginning of their lives and many
died before six months of age.
 
*There was no fourth generation in any of the three processed
food groups. Either the third generation parents were sterile or the
fourth generation cats died before birth.
 
Remember, all four generations of the raw food groups were
healthy throughout their normal lifespans.
 
that only diets containing raw milk and raw meat produced optimal
health: good bone structure and density, wide palates with plenty of
space for teeth, shiny fur, no parasites or disease, reproductive ease
and gentleness.
 
Cooking the meat or substituting heat-processed milk for raw
resulted in heterogeneous reproduction and physical degeneration,
increasing with each generation.
Vermin and parasites abounded.
Skin diseases and allergies increased from 5% to over 90%.
Bones became soft and pliable.
Cats suffered from adverse personality changes, hypothyroidism and
most of the degenerative diseases encountered in human medicine.
They died out completely by the fourth generation.
 
The changes Pottenger observed in cats on the deficient diets 
paralleled the human degeneration that Dr. Price found in tribes
that had abandoned traditional diets.”
