Patricia - 10 Jun 2004 05:48 GMT
My Farfou has been diagnosed with struvite crystals.
After 5 days at the vet he came back home. I am supposed to feed him
Hill's c/d prescription diet but he refused to touch it and it has
been 3 days now ...
He is hungry and would actually eat his normal dry and wet food.

I try to lure him with fresh chicken, which he eats a little bit.
He was always eating better quality canned and dry Petguard or
Wellness.

I would like to try the IVD prescription food.

Does anyone have (good or bad) experience with this brand?

Or advise how can I make him eat the c/d food?

ascorbic acid will increase the acidity of his urine and break down the
struvite chrystals. just break up and add to his food and keep an eye on how
much he eats and spits out. you will probably find he eats some and realises
and spits out the rest but enough gets eaten to work.

Just out of curiosity, do you have a source for this information?

Plain old Vitamin C?   Do you have any more information or links you
could provide?  I have a male that blocked once and is now on SD-c/d.

I did have when I researched it. I don't have the links now as it isn't a
problem for my cat now that he gets ascorbic acid. I think you can buy
vitamin C that isn't ascorbic acid and that type doesn't increase the
acidity level.  There was a report when I looked from a lady that feeds a
colony of feral cats in New York and she had lots of first hand anecdotal
evidence of the cats being far better once she added ascorbic acid.
generally healthier and less prone to infection. Vets don't recommend it as
its really cheap and Hills or comparable food is really expensive.

This is the active ingredient in Hills to cure struvite crystals and you can
buy it instead of Hills prescription (Hills is just ordinary pet food plus
this stuff).......

Its cheap in the USA but expensive here. see thread below for info.

Icarus - again that is incorrect. It is a great deal more complicated
that simply adding urinary acidfiers to a diet. For that reason
testing is done on foods to determine the APR value of a food. APR
(Activity Product Ratio)is a method of looking at the bio reactors and
every constituent involved in the process. Just removing magensium
and/or adding urinary acidifiers is not the best possible choice.

true Steve but I wasn't suggesting that you should stop feeding the cat and
simply give it methioform. I was assuming that the reader of my posting
would have a basic knowledge of a cat's needs (like they need to be fed) and
would give methioform PLUS a quality cat food that gave a good balance. That
works out significantly cheaper than using Hills or another prescription
food.

Vet's don't want to tell you this as they make nearly ?5 per bag on each bag
of prescription diet food that they sell; an average vet's practice  sells
maybe > 100 bags a week to their pet owners so that's an easy  profit each
week with very little effort on the part of the vet. I know this as I have
spoken to more than one veterinary nurse working in different practices.

The only time you post that you work for Hill's is when you're called on it,
especially when you're bashing other pet food companies, and making up false
information about them.

Icarus,
 Vets don't "want to tell you this" because it simply isn't true. Not
because of some profit motive. I do not have much familiarity with
vets in the UK, but I doubt seriously if they are a breed apart from
US vets. What you are proposing is medicine circa 1950 when we only
had methioform tabs and ammonium chloride tabs to alter urine pH.
Since that time we have learned a great deal more about the
pathophysiology of struvite and CaOx stones and FLUTD in general.
Altering urine pH and reducing magesium (in struvite only) does not
resolve all the issues in FLUTD cats. It _may_ work in some subset of
cats, but neither you nor I can predict which cat 1950's medicine will
work on and which ones it will not.
 Further your suggestion that 5£ profit in some way is innapropriate
is pretty silly. Buying a decent quality food and then adding a
supplement almost always ends up being more expensive in the long run.
There are numerous wellness pet foods on the market that cost
considerably more to feed than Prescription Diet c/d. Choosing one
that is of good quality will inevitably mean the overall cost of
feeding the cat is less than buying the diet designed for the disease
entity in the first place. That's of course assuming you could find a
wellness diet on the market that met the minimal parameters in the
first place. It might be interesting to take a look at just this
process. How about providing for me a cat food brand sold in the UK. I
will need the following information and I will do the math to dtermine
the actual costs.

1. Name, brand, of the suggested cat food
2. Size of the bag/can
3. Cost of the bag/can
4. Kcals ME per gram/kg/ounce/pound/can etc. If Kcals are provided per
cup of dry food - then how much does a cup of the food weigh.
5. Magnesium level (must be less than 0.065% dry matter basis)
6. Suggested supplement name
7. Contents of supplement - (mgs methio, ammonium chloride etc)
8. Cost of supplement package
9. Number of tablets contained in the package.
10. Supplement company reccomended dose per day.

About time for the periodic legalese.
While I have been teaching small animal clinical nutrition to
veterinarians and thier staff members for over 20 years as an employee
of Hill's Pet Nutrition - ANYTHING I say here is my personal opinion
alone and should not be construed to represent the company I work for
in any way shape or form.

The way vetrinary prescirption drugs are provided within the UK is currently
being researched by the EC as the profit margins within the UK are
excessive.  As an example ......
dl-methionine (trade name methio-form) only costs ?9.00 maximum for 150
500mg tablets in the USA but it costs ?60 here in the UK  for equivalent
quantity/prescription strength from a UK vet !!!

Hills costs ?15.95 from a vet for a 2kilo bag and costs them ?11.00. They
have a captive audience and make huge profits from recommending it. Many
practices make in excess of ?50,000 per year profit selling it and
consequently have no insentive to recommend any alternative approach. I dont
think thats very fair and apparently neither does the EC.

Its a good idea to state that you work for Hills as you have an 'interest'
too, thank you.

However, we have got bogged down on Vitamin C whereas my view is that any
good balanced food plus Vitamin C and methionine will do the trick. After
all, what is the active prescription ingredient in Hills ? There is an
interesting breakdown of what's in various cat foods on this website.....
felinecrf.org. You are arguing that Hills is the best as it provides the
best balance overall with the lowest ash etc.... why don't you (I am sure
you have already) look at the non-prescription cat foods shown there and
take two of the most balanced and add VitaminC and methionine to the daily
feed and then do your magic calculations and tell us which is the best ???
I am sure we can trust your professional integrity to be fair in the
appraisal. If they lack something, tell us what and give a fair comparison
with Hills.

After all you are not here representing Hills so what would you lose ?

My main point was that people go to a Veterinary Practice for professional
advice/consultancy and help. However, the current system in the UK gives the
vet such a large financial benefit  that it would be surprising if they were
impartial. This is rather unfair as the dice are loaded towards the vet
always recommending a long term prescription diet because of the financial
income they gain from giving that advice. People expect professional help
but instead end up talking to a salesman.

For some reason Google is notletting me post a response to your
message, so I'll append it here.

I'll work with just the one as it illustrates the point, the remaining
are merely hypothesis without any proven factual data to support them.

We have to learn to understand what is curently being called Evidence
Based Medicine. What that means is that you look at a variety of
different pieces of information and grade eachone based upon certain
aspects. This has been done in human medicine for about a decade and
is just now getting some attention in veterinary medicien. See the
upcoming AVMA journal for an article on Evidence Based Veterinary
Nutrition.

Evidence base dmedicine requires we judge the valueof any given
statement based upon a set of criteria. In descending order.

Evidence Based Medicine Grade 1
Peer reviewed, published, clinical trial, in the animals for which the
product is designed (not rats when you are applying it to dogs), in
animals with naturally ocurring disease, double blind, controlled,
often crossed studies, (animals exposed to both criteria at both
groups having the same experience) or a meta analysis of a large group
of lower grade studies.

Evidence Based Medicine Grade II
Peer reviewed published data, in an animal not that of the specie the
drug or diet is going to be used for, or in surgically created
disease, double blinded, and controlled, or a meta analysis of a small
group of similar studies.

Evidence Base Medicine Grade III
A study done, Not published in peer reviewed journal, not in the
animal for which the product is designed, sugicallyinduced disease or
the use of a laboratory animal with a pre-disposition to that disease,

Evidence Grade Medicine Grade IV
Hypothesis, a logical theory, an idea, a position paper, not published
in a peer reviewed journal.

The evidence you cited all belongs to the bottom of the heap, none of
them were a peer reviewed published study, almost all are opinion and
hypothesis. The one study I gave you is a Grade II study, it fails
being a Grade I study since the animals used were not crossed and then
subject to the opposite action.  All of the information you have
posted fails to make it to even Grade III level. Most are opinion and
hypothesis without any foundation in fact.  Grade 1 Evidence Based
medicine trumps all others until another Grade 1 Study shows
otherwise. When you fail to grade the studies you have, or evaluate
the level of information provided it is quite easy to accept
hypothesis and then be in error. I personally have some knowledge of
the attempts to use vitamin C as a urinary acidifier. I was involved
in a non trial and clinical study that showed that it would take just
about 1 gm per pound to alter the urine pH by 1 point. You will never
get a cat to ingest 1 gm per pound, it's simply impractical and ill
advised.

That is incorrect, it is impossible to get a cat to eat enough
ascorbic acid to move the urine pH enough to be of any value
whatsoever.

oh well I would be interested to know what you base this on Steve. There are
various websites that say you are mistaken and that a cat's system  absorbs
up to 250mg of ascorbic acid daily (any more and it just flows through the
system)  and that it does cause the urine to acidify.  This is an
interesting website.... http://www.neighborhoodcats.org/info/nutrition.htm
also try reading/referring to the books mentioned there.

Icarus,
  Below is one of several published peer reviewed studies showing
that vitamin C has NO effect on urine pH. Old wives tales and internet
wishful thinking do not change the facts.

Struvite stone dietetics: 1. Effect of different feed rations on the
urine pH value of cats]

[Article in German]

Kienzle E, Schuhknecht A.

Institut fur Tierernahrung, Tierarztlichen Hochschule Hannover.

In this investigation the base excess of cat foods (sum of alkalogenic
compounds calcium, magnesium, sodium and potassium minus sum of
acidifying compounds phosphorus, chloride, methionine and cysteine;
base excess in mmol/kg dry matter =
Ca*2+Mg*2+Na+K-(met(-)+cys)*2-P*2-Cl) as a method of predicting the
influence of food on the urinary pH was tested. The base excess and
the effect on urinary pH (feeding experiment with 4 to 6 adult cats
per trial) was determined in 10 commercial cat foods (3 moist, 3 dry
type foods, 4 struvite diets) as well as the influence of several
additives (CaCl2, CaCO3, Ca-lactate, CaHPO4, phosphoric acid in 2
doses, NH4Cl, ascorbic acid). After the intake of commercial cat foods
the mean urine pH ranged between 6.58 and 7.89, after the intake of
struvite diets it ranged between 6.36 and 7.57. The addition of
Ca-carbonate or -lactate led to a significant increase of urine pH,
Ca-phosphate and ascorbic acid had no effect, while Ca-Chloride,
phosphoric acid and ammonium chloride led to a decrease. There was a
highly significant correlation between the base excess in the food (x;
mmol/kg dry matter) and the mean urine pH (y; y = 6.72 + 0.0021 x; r =
0.96**).

Steve I am posting this information again as you seem to be rather selective
about what you answer on here and what posts you chose to notice :)

Please explain why these folk are wrong. Its not me saying that it does
increase acidity its various responsible places on the web.

> That is incorrect, it is impossible to get a cat to eat enough

Steve, your statement appears to be incorrect. Please see the quotes below
for information. Basically Vitamin C does acidify urine as it passes through
the system.  Some reports say it does significant good in reducing struvite
crystals and cannot do a cat ANY harm whatsoever by being added to a cats
diet.  It is an known fact that struvite crystals occur due to cats urine
being too alkaline, Vitamin C makes a cats urine more acidic so what is your
point please ?

       Vitamins C and B complex are water soluble. Water soluble vitamins
are not stored within the body except in small amounts. It is for this
reason that the fat soluble vitamins pose the biggest threat if
oversupplemented.

     The body tissues do not readily store water soluble vitamins and when
fed in excess, they are easily eliminated from the body via the urine.
Because they do not accumulate within the tissues, there is minimal risk of
toxic effects. In fact, we are not aware of a single toxicity case ever
having been documented in either cats or dogs.

     Vitamin C

     Vitamin C has been thought to prevent hip dysplasia, cure feline
leukemia, and prevent urinary tract infections.  We have worked with several
animals that had clinical hip dysplasia, that when given high levels of
vitamin C, seemed to exhibit fewer signs of joint pain. It did not cure the
condition, but it did seem to allow the patient to better live with the
problem.

     In the case of bladder infections,  we believe that vitamin C is
unusual in that it is excreted unchanged totally via the kidneys, and it
therefore, acidifies the urine. This makes the bladder a much less
hospitable place for bacteria to live. Most of the bacteria that cause
cystitis (bladder infection) survive much better in environments that have
an alkaline pH. Therefore, by acidifying the urine with vitamin C, these
organisms are often eliminated.

     As far as its use in viral diseases like the common cold or feline
leukemia, in all honesty, there is little evidence of its value. At the same
time, we would readily admit that vitamin C can do no harm when used. As we
stated, it is excreted unchanged via the urine.

     Forms of Vitamin C: We know that vitamin C exists in two forms: as
dehydroascorbic acid and as ascorbic acid. Ascorbic acid is easily
hydrolyzed (mixed with water) and therefore, it is readily absorbed through
the intestinal wall. Likewise, it easily enters the urine to exit the body.
Very little is stored within the body and the minute amount that is, is
contained within the adrenal gland. Ascorbic acid can be fed or it can be
manufactured within the body from glucose.

     Therapeutic Uses: Ascorbic acid plays many important functions in bone
formation. It is involved in bone growth as well as bone mineralization.

     Vitamin C has been used with varying degrees of success in helping
prevent the formation of some bladder stones in cats and dogs. The vitamin C
makes the urine more acidic and maintaining an acid urine helps discourage
the creation of most stone types.

     In conclusion, vitamin C is widely used as a supplement in growing,
pregnant, lactating, stressed, and working pets. There are numerous vitamin
C supplements available. There is no concern for vitamin C toxicity.

     Vitamin C has been used with varying degrees of success in helping
prevent the formation of some bladder stones in cats and dogs. The vitamin C
makes the urine more acidic and maintaining an acid urine helps discourage
the creation of most stone types.

     In conclusion, vitamin C is widely used as a supplement in growing,
pregnant, lactating, stressed, and working pets. There are numerous vitamin
C supplements available. There is no concern for vitamin C toxicity.

If he's eating something that acidifies the urine, it's probably okay to
also give him some of his usual wet food.  The prescription diet has an
acidifier so if he's eating some of that and some of his usual, that should
be enough.  Cats need to eat regardless, they can get serious health issues
if they don't eat for too long.

I can't blame him for not eating the Hill's, the ingredients in there are
pretty icky.

> Does anyone have (good or bad) experience with this brand?

I've never tried IVD (I don't think that's available where I am), but my cat
was diagnosed with the same thing and I managed to find another premium
kibble, Wysong "Uretic" formula, which does the same thing as the Hill's in
that it acidifies the urine which is what you want because it dissolves the
crystals.  Both have the same acidifying ingredient (DL-Methionine or
something like that).  But the Wysong has much better ingredients than the
Hill's.

> Or advise how can I make him eat the c/d food?

Give him his Wellness wet food and maybe some prescription kibble, as one
possibility, or mix c/d wet and Wellness wet food.

I used the Wysong dry, and also served lots of Wellnes wet food, and added a
little extra water to his wet food, and that has done the trick (3 weeks
later he was declared crystal free).  I also gave him a homeopathic remedy
to help with the acidification.

But now I'm switching all my cats to a raw food diet because that keeps the
urine in proper balance, just slightly acidic, which will help prevent the
problem from recurring.  If they stay on the prescription stuff with
acidifiers it can cause another type of crystal that forms in a too-acidic
urine!  So acidifying is what you want short-term to get rid of the struvite
crystals in there now, but it's not a good idea long term to have the urine
too acidic.

Hope this helps and I know I've rambled on a bit, but I just went through
the same thing with my cat.

Look out, LOL, Steve Crane (works for Hill's) will be posting soon how bad
Wysong is (or any other brand that isn't Hill's).

I've been feeding my cats a raw diet for 4 years now and they've never had
urinary problems thank goodness.  I've heard once they develop the problems,
it's hard to get them right again.  Glad to hear your cat is doing well :)

What is the minimal amount of food (can) a 14lbs cat needs to eat so
that he didn't get badly sick?

Wysong Uretic? Dry?
I thought I should avoid giving him dry food, since this is one of the
cause for stuvite crystals formation ...

Which homeopathic remedie did you use?

Yes, I have started feeding them raw chicken. But I still have to work
on the supplements. I will buy a already prepared suppements, I was
recommended to use from a yahoo group.

I agree and I really don't want him to get the oxalate crystals.

Thank you very Sherry for sharing your experinece with me/us.

interested in seeing any published peer reviewed data you might have.

I always say the proof is in the pudding.  Out of the almost 1,000 members we
have in our raw feeding list, the cats that have been fed for a while on a raw
diet do not experience urinary tract problems or urinary crystals.  However, we
do see people who feed a commercial diet join the list because their cats have
urinary problems and/or crystals and are seeking to switch their cats to a raw
diet because the commerical foods including "prescripton" foods aren't working,
especially long term.

What about fresh, cooked foods?  My cats are definitely NOT interested in Raw
feeding.  The dogs do great on it, and I would be happy to switch the cats, but
I've tried a few different attempts and have been met with glares of "you
expect us to eat THIS?".  As it is now, the cats are eating canned food only,
mostly Neo-Diet.

Yeah I know, it can be very hard to switch cats to a raw diet.  Fresh cooked,
as long as it's balanced and has the right supplements, is probaby better than
commercial in that the ingredients are going to be a higher quality, and you
know what the ingredients really are.  I've never heard of Neo-Diet.

Yeah, I figure that as well, and probably better recieved.  There are a number
of homemade CRF diet recipes online - think I'll start trying them when I get
back from vacation - don't need the petsitter to be trying to figure that out!

> I've never heard of Neo-Diet.  

It's Hi-Tor's CRF diet, instead of Hill's K/D.
Much more palatable.

No - you can get it in some specialty pet supply stores (or online of course).
Its'a an alternative to K/D, which many cats seem to turn their noses up at!

known cat food in the UK is Gone Cat ???? Its apparently well known for
causing kidney/urinary problems.

It makes perfect sense that cats would do well on raw food. Feral cats only
eat by tooth and claw after all. There's no vegetables/ cereals or cooked
food there.

Have a look at felinecrf.org for lots of good information (n.b. it doesn't
start www. on the front).

Also http://home.earthlink.net/~jacm2/id1.html describes cat's nutritional
requirements in detail and suggest the suitability of raw food for cats. Its
been reviewed by the American College of Veterinary Nutrition (ACVN) so its
definitely accurate/factual.

I have nothing against a raw diet; I?ve heard too much good to say
that it is bogus. But, Stray/feral cats don?t always live on what
they catch - they are opportunistic and will eat garbage if that is
all there is.

That's a really great article.  I have seen it before but it's always good to
read it again.  Wish more vets were as knowledgeable about nutrition.

I hadn't realised there was so much politics in feeding cats.

Its not the cost, its what's best for them and do it for the money and don't
act professionally. Its sad as they are suppose to be independent and they
aint.

oooops, that was supposed to say.......

Its not the cost, its what's best for the cat but vets make recommendations
on your cat's diet according to the money they earn and don't  act
professionally.
