IAMS is a pet food company that was bought by Procter & Gamble
(P&G) in September 1999. In addition to P&G's animal testing practices,
IAMS - as a company in its own right - has a legacy of performing invasive,
painful and lethal experiments on animals.
These experiments are conducted on a wide range of animals: cats, Beagles,
Great Danes, German Shepherds, Sled Dogs (Huskies), Cocker Spaniels, Miniature
Poodles, Doberman Pinschers, dogs of "mixed breed", pigs, rats
IAMS' website has stated:
"Animal nutrition is our life's work, but it's only one contributing
factor to a pet's well-being. That's why we built the Paul F Iams Technical
Care Facility. It's home to a group of dogs and cats that helps us to
understand the physical and emotional needs of companion animals.
"The cats and dogs in our animal care facility are treated
with the greatest respect. Just like your pet, they're given names and
groomed and played with daily..."
A proud exposition of the "extensive research" that IAMS puts
into the development of new products explains:
"We also fund research efforts outside our walls. The Iams
Company underwrites studies of companion animal nutrition, dermatology,
geriatrics, kidney disorders, allergies and much more."
IAMS uses the data from these studies to support nutritional claims which
they use to market their products, it is less forthcoming about what these
studies actually involved. In fact, buried in obscure scientific publications
are the details of experiments on at least 460 cats and dogs supported
by The Iams Company - cats and dogs just like our cherished companions.
But these experiments were not designed to help the animals involved.
These innocent victims were simply used as disposable objects - a means
to an end.
IAMS - the awful truth
1. Kidney failure and death inflicted on dogs
The first study referred to in the Express article tells how:
"...24 young dogs had their right kidneys removed and the
left partly damaged to investigate how protein affects dogs with kidney
failure. Eight dogs were killed to analyse the kidney tissue.
Dogs which became sick were not treated because it would have undermined
the test results."
This study was part-funded by The Iams Company and reported in White
J. V. et al, "Effect of dietary protein on functional, morphologic,
and histologic changes of the kidney during compensatory renal growth
in dogs", Am J Vet Res, Vol 52, No. 8, August 1991, pp. 1357 - 1365
(No.2 in tabulated file).
In the study, 24 young adult mixed breed dogs were given 'acute' (meaning
'rapid onset, severe symptoms') renal [kidney] failure. This was achieved
by cutting the dogs twice in the abdomen area, removing one of the kidneys
and destroying 75% of the remaining one by cutting off the blood supply
to that proportion of the kidney. Thus the dogs were left with only one-eighth
of normal renal function.
As many guardians of companion animals know only too well, kidney failure
can cause terrible suffering. If kidneys don't function properly, waste
products end up in the blood rather than being excreted. This blood poisoning
can cause serious and fatal illness. Dogs with kidney failure may suffer
"depression, loss of appetite, thirst and vomiting. The back may
be arched, and there may be stiffness. There is fever, and sometimes ulcers
are present in the mouth." (Black's Veterinary Dictionary: 292)
After renal failure was inflicted on the animals, 22 of them (it doesn't
say what happened to the other two, maybe they died during the renal failure
procedure?) were studied for up to 14 months as their kidney slowly regained
some lost function.
The paper states:
"Dogs that became dehydrated were administered replacement
fluids... Other supportive treatment was not administered."
Four dogs had to be put down during the experiment because of "severe
uremia" ('the presence of excessive amounts of... waste products
in the blood. ...their accumulation in the blood occurs in kidney failure
and results in nausea, vomiting, lethargy, drowsiness and eventually death.'
Oxford Medical Dictionary. Black's states that in cases of uraemia 'death
may be preceded by convulsions and unconsciousness.')
After seven months, eight dogs were killed so the condition of their
remaining quarter kidney could be examined. Seven months later the remaining
ten dogs were killed.
2. Cats cut open and killed
This is the second experiment referred to in the Express piece:
"In another experiment, the stomachs of 28 cats were exposed
so scientists could analyse the effects of feeding them fibre. The animals
were operated on for at least two hours and then killed."
This study was also part-funded by IAMS and was reported in Bueno A.
R. et al, "Feline colonic microbes and fatty acid transport: effects
of feeding cellulose, beet pulp and pectin/gum arabic fibers", Nutrition
Research, Vol. 20, No. 9, pp. 1319-1328, 2000. (No.1 in tabulated file)
The study used "twenty-eight adult female cats... All cats were
short-haired females, 2 to 5 years of age and purchased from a government
approved class-A distributor [Eds note: i.e. a vivisection breeding establishment]".
The cats were split into groups of two or three, housed in indoor enclosures
and fed differing diets for 2 to 3 weeks. One of the cats "was removed
from the study for an unthrifty appearance." ['Unthrifty' is not
a term found in medical dictionaries. Animals will be excluded from experiments
if they differ from the rest of the group in a significant way, e.g. if
their state of health is different, as this would undermine the design
of the experiment. It doesn't state whether or not the cat was killed.]
On the day of the "colonic perfusion study" the animals were
anaesthetised and "maintained at surgical anaesthesia", laid
down on their sides, and their abdomens cut open. A catheter placed into
the colon and a tube placed in the animals' rectum. Their bowels were
then flushed empty.
For two hours, a test solution was pumped through the cats' bowels and
collected every ten minutes.
This paper does not say whether the animals were killed before, during
or after the next stage of the study - the removal of parts of their large
intestine systems (caecum and colon), as this part of the study was reported
in a different paper.
Although most of the cats may not have endured severe illness and suffering
during the study, keeping animals in small indoor environments inevitably
raises concerns about their ability to fulfil psychological needs, and
the vivisection, killing and dismemberment of the cats are destructive
and murderous acts.
3. Cats made obese and then starved - liver damage observed
This is the third experiment mentioned in the Express:
"The research team sterilised 24 female cats, which were over-fed
until they become obese. They were then starved on a crash diet and
when they had lost a third of their weight their livers were examined
to investigate the link between weight loss and liver disease."
This IAMS-supported study is reported in Ibrahim W. H. et al, "Effect
of dietary protein quality and fatty acid composition on plasma lipoprotein
concentrations and hepatic triglyceride fatty acid synthesis in obese
cats undergoing rapid weight loss", AJVR, Vol 61, No. 5, May 2000,
pp.566-572. (No.13 in tabulated file)
The paper states: "Twenty-four female cats between 2 to 5 years
old were purchased from a commercial dealer (Harlan Sprague Dawley, Indianapolis,
Indiana.) Cats were individually housed..." After a week the cats
were "ovariohysterectomized". They were then fed on a "high
quality energy dense diet" (Eukanuba, produced by The Iams Company)
until they became clinically obese (minimum of 30% over normal body weight)
and could not gain any more weight - this point was reached at about eighty
days. The researchers themselves note that:
"Obese cats are reported to be at greater risk for development
of certain diseases, such as osteoarthritis, ligament injuries, perineal
dermatitis (inflammation of the skin around the genitals), diabetes
mellitus, lower urinary tract disease, and cardiomyopathy (heart disease).
Mortality risk is also increased."
None of the cats are reported to have died during the study period as
a result of obesity, though their clinical condition during their obesity
was not commented upon.
Once the cats had reached obese proportions, they were placed on a diet
that only provided them with 25% of their "energy requirements for
7 to 8 weeks, or until cats had lost 30 to 40% of their obese body weight".
This was to mimic "rapid weight loss in cats". Two of the cats
did not even manage to consume a quarter of their nutritional needs.
The researchers themselves acknowledge:
"Safe, rapid weight loss in cats can be difficult, because
cats have special dietary requirements that appear to make them more
susceptible than other species to HL."
HL stands for hepatic lipidosis, a disease of the liver which results
in impaired liver function. The paper reports that the study caused three
cats to develop HL during the weight loss period."
The cats also had to undergo three liver biopsies during the study.
4. Severe allergic reaction provoked in husky puppies
The Express article states:
"The company also sponsored research in which 14 husky puppies
were repeatedly injected with live vaccines and allergy causing pproteins
for the first 12 weeks of their lives. They developed permanent illnesses
in the test, which was designed to see how severely allergic they would
This description is based upon an IAMS-funded study described in: Olson
M. E. et al., "Hypersensitivity Reactions to Dietary Antigens in
Atopic Dogs", Proceedings of 2000 IAMS Nutrition Symposium, p. 69-77.
(No. 24 in tabulated file.)
This paper presents a study where 11 "Crossbred sled" new-born
puppies were repeatedly (10 times over the first 85 days of life) injected
with attenuated live virus vaccines containing Distemper, hepatitis and
parvovirus together and subcutaneous injections of the food antigens.
Another three animals were not sensitised but were subjected to the same
procedures as the other dogs.
Skin tests were performed on the animals when they were six (to see if
they had been "successfully" sensitised) and ten months of age.
No mention of even a local anaesthetic (anaesthetics are referred to elsewhere
in the paper - e.g. in describing the gastroscopic examinations). Four
concentrations of each food allergen (soy, casein and chicken liver) were
injected "intradermally". In most case the lowest concentration
caused a skin reaction. The highest concentration that the dogs were injected
with was 100,000 times stronger than the lowest concentration (0.02 micrograms
vs 2000 micrograms). Histamine (causes inflammation) was also injected
as a positive control, and saline as a negative control. Some of the higher
concentration injections caused weals (similar to swellings caused by
nettle stings or hives) averaging over a centimetre across.
Similar sensitivity tests (gastroscopic food sensitivity) were conducted
by injecting the allergens into the stomach lining of the puppies. These
were performed under anaesthetic. Once again, the higher concentrations
caused marked allergic reactions: moderate to severe inflammation characterised
by fluid filled swelling and redness caused by expansion of blood capillaries
(erythema & oedema).
The results of these skin and stomach tests were reflected in the health
of the allergic puppies when they were placed on allergic diets for a
month. All eleven puppies:
"developed moderate to severe diarrhea and lost weight (data
not shown). Furthermore 8 of the 11 sensitized dogs demonstrated dermatological
reactions that included hair loss and pruritis [itching, similar to
that found in eczema]... Clinical signs developed within the first week
of feeding the sensitising diet and persisted as long as the diet was
provided... Moderate to severe pruritis, with and without lesions, was
also observed in sensitised dogs receiving diets containing the allergens."
5. Skin wounds inflicted on 36 dogs and puppies
The final experiment mentioned in the Express describes how:
"Twelve huskies, 12 poodles and 12 labradors were regularly
given chest wounds to see if diet could affect fur regrowth. This was
justified in the study on the grounds that 'dogs are enjoyable to touch
and look at. Dogs with coat problems are simply not handled as much.'
This IAMS-supported study is reported in Credille K. M. et al, "The
Role of Nutrition on the Canine Hair Follicle: A Preliminary Report",
Proceedings of the 2000 IAMS Nutrition Symposium. (No.23 in tabulated
The study involving repeated skin biopsies from 36 puppies and older
dogs (12 Siberian Huskies, 12 Minature Poodles, 12 Labrador Retrievers).
Each of the dogs had two 6mm sections of their skin removed under local
anaesthetic every three weeks for 18 weeks. One would imagine this would
cause soreness and discomfort to the dogs afterwards, each of which would
end up with 12 wounds on their bodies after the 18 week study.
The researchers report that:
"Overall, there was little to distinguish the dogs fed the
high- and low-quality diets;"
6. Finally... SmithKline Beecham helps supply dogs for IAMS vivisection
In an IAMS-funded lethal experiment on 15 healthy beagles which was reported
in 1996 and was similar to the second experiment described above, the
authors of the report "express their thanks to SmithKline Beecham
Animal Health Laboratory... for their support in development and use of
the research animals." (Hallman J. E. et al, "Colonic mucosal
tissue energetics and electrolyte transport in dogs fed cellulose, beet
pulp or pectin/gum arabic as their primary fiber source", Nutrition
Research, Vol. 16, No. 2, pp. 303-313, 1996 (No. 9 in tabulated file).)
SmithKline Beecham is now known as Glaxo SmithKline. It is one of the
world's largest pharmaceutical companies and has a direct influence on
UK Government policy, including animal experimentation policy, for which
it has lobbied for a relaxation of regulations.
Dan Lyons, director of Uncaged Campaigns, comments:
"No reasonable person can ever accept the conduct of painful
and lethal experiments on one animal in the distant hope that some information
might emerge that might be useful for another animal. After all this
is similar what the Nazi's did - experiment on some humans supposedly
to try to benefit other humans. I look after a wonderful cat, Zorro,
and I'm deeply concerned for his welfare - but I could never, ever think
it right to perform painful and deadly experiments on another cat even
if I thought it would benefit Zorro. It's nasty, violent and unfair.
"There's nothing wrong with trying to find out how to improve
diets for animals, but the right way to do that is to observe the same
guidelines that exist for medical research involving children. Samples
and readings can be taken during veterinary or medical treatments that
are conducted for the benefit of those individuals. Post mortem studies
can be carried out if tragedies occur and children or animals die. Other
non-invasive and harmless observations can be made. But it is deeply
hypocritical and unethical of IAMS to buy animals bred specifically
to be vivisected, and then inflict suffering and death on them.
"If IAMS were genuinely concerned about animal welfare they
would not be actively damaging and slaughtering innocent animals. We
call on them to stop vivisection immediately and adopt cruelty-free
