Several years ago my cat was diagnosed with kidney disease.
Her symptoms were a high water intake, lots of urinating in the litter, fairly 
frequent vomiting and hard as rock (and apparently painful) stools.
After discussing her with a local homeopathic vet, I stopped all shots, 
vaccines, and tick and flea repellents.
We put her on some recommended homeopathic remedies and she seemed to improve 
for a few years.
About two years ago when she was 12 years old she started looking listless and 
would not eat, so I took her to a local animal hospital who diagnosed her with 
a kidney infection.  This immediately followed having the interior of our house 
painted, so I think the environmental pollution got to her.
They recommended an antibiotic which I did give to her.  However, she did not 
improve.  Her temperature soared to 107 over the next couple of days and on 
several occasions I thought she might have died because she was completely 
unresponsive when I tried to wake her.
She would not drink or eat, so I started giving her CS in a dropper.  She would 
choke on it, but some went down, and I continued this every hour until she was 
getting more and more CS.  Eventually she started to move again and would then 
drink CS from a bowl, so we were able to discontinue the droppers.
Within a week from the initial attack, she was on the road to recovery, 
although a return to normality took about two more weeks.
The vet told me that cats with kidney disease are more prone to kidney 
infections, so from then on I have given her only CS to drink.  And she drinks 
a HUGE amount of it, I would say at least 10 to 12 ounces a day, sometimes 
more, seldom less.  Since she only weighs nine pounds, this equates to roughly 
seven percent of her body weight.  If a 155 LB human drank an equivalent 
amount, he or she would be drinking about 10 LBS of CS per day, or about 5 
quarts.  The absolute amount that she drinks is about the same as what I take, 
but the amount per lb of body weight is much, much greater.
She has been doing this for two years now and, although she is showing signs of 
age, she has remained healthy, alert, and without any sign of kidney infection. 
 A human drinking so much CS would be concerned about argyria, but since she is 
covered with black fur, this is not a concern (do humans with dark skin worry 
about argyria?).  I initially worried about her drinking so much CS since it is 
off the charts of what people normally take, but it seems only to have done her 
a lot of good.  I know that age and kidney disease will claim her eventually, 
but I think she is a testament to the beneficial effects of CS usage and proves 
that it has little if any toxicity even in very large doses.
