Not ONE WORD you posted shows that phosphorus "causes" renal failure n
healthy cats and, since I said that it would be contraindicated in cats
with kidney issues, how could you disagree? And what exactly is
excessive? Because Hills says it is it must be so? Where are the studies
that prove what level is "excessive" in healthy cats? And while you're
at it, explain how the perfect food for the cat (a mouse) is higher in
phosphorus than commercial cat foods yet is the optimal diet. Show some
evidence that higher phosphorus *causes* renal failure in healthy cats
or STFU.

Good Grief Megan,
NOBODY has ever said excessive levels of phos CAUSES renal
failure. That is not the point and never has been. The objective of
being healthy is to _avoid_ certain risks. I wear a seat belt because
there is a risk associated with not doing so. We know that there are
risks associated with certain behaviors - sky diving is a risk. The
act of sky diving does not mean that sky diving CAUSES your parachute
to fail and your body to hit the ground at 80 miles per hour. Feeding
a food with excessive levels of phosphorus is a clear, and totally
unnecessary risk, especially if you are feeding an older kitty and are
not getting the ERD testing done. It is a well known and well
documented RISK, not a cause.
When you can show me your crystal ball that allows you to know
which cats will eventually die of renal failure, then we can eliminate
the risk by feeding excessive phos diets to the segment of the
population of cats that will not eventually succumb to renal failure.
So far I haven't seen anybody with a crystal ball service letting you
know which cats are going to die of renal failure.
Renal failure is not detected until the kidney is +70% destroyed
and the disease is progressing toward death. You could be feeding a
cat with 50% of the kidney already destroyed and never know it. Your
cat with no symptoms and with perfect lab results could be slowly
dying of renal failure and you cannot even tell it is happening. At
this stage feeding a high phos diet will indeed CAUSE the acceleration
of the cats death.
