Colloidal silver, especially in combination with colloidal gold, has had some very good success against cancer. Colloidal gold essentially encapsulates the cancer tumors and colloidal silver.
Personally I would not rely on silver and gold alone. Inositol/IP6 has had very good success against tumors in animals, as has oleander extract.
Insofar as kindey problems, silver does help in tissue repair and contrary to what the above poster said, there is little risk of kidney damage from silver. There is a much greater risk of kidney damage from flouridated water and water that comes out of a garden hose.
One thing silver does to virtually all animals - restore them to health and vitality as if they were years younger. If you put two bowls of water side by side and add silver to one, THAT will be the one the animal prefers virtually every single time - proving that animal instincts are better than "some" posters advice.
I think that important keys for both animals are: good diet, removal of all herbicides, pesticides and other toxins from their environment, and quality drinking water
Here is some great info from Shirley's Wellness Cafe (just about my favorite place for our furry friends):
Presumably, the term “chronic kidney failure” suggests that the kidneys have quit working and are, therefore, not making urine. However, by definition, kidney failure is the inability of the kidneys to remove waste products from the blood. This definition can occasionally create confusion because some will equate kidney failure with failure to make urine. Kidney failure is NOT the inability to make urine. Ironically, most dogs in kidney failure are actually producing large quantities of urine, but the body’s wastes are not being effectively eliminated.
"Kidney failure" might mean compromised, overworked kidneys - or it might mean damaged kidneys (i.e., severe, chronic renal failure). Kidneys can be damaged - irreparably, so the veterinary information says - by a whole slew of environmental poisons and veterinary treatment drugs, and via other disease forces as well (such as kidney infections, diabetes, leptospirosis, cancer, as examples). And kidney problems can be inherited (especially by certain breeds). (By the way, I've read that kidney failure is supposedly easier to treat in cats than in dogs.) Kidney failure (renal disease - increased thirst, dehydration, loss of appetite, urination changes, maybe nausea and pain) is common in elderly pets - systems do fail as we get older, whoever we are. But the kidneys are one of the critical factors in eliminating toxins from the body - and they become less efficient with age, and with toxin loading. (Which can be a problem at any age, just like with humans.)" more on kidney failure
Russell Swift, DVM on kidney disease - "Fortunately, since I have turned to a holistic approach to wellness, I have seen many dogs and cats outlive their death sentence by years. I believe there are three major reasons for kidneys to degenerate and eventually fail: 1) poor quality nutrition, 2) toxicity and 3) chronic disease. I have discussed in many previous articles the failings of processed foods. Inadequate and improper protein sources and low moisture content (of dry foods) are the two major kidney stressors I believe occur in commercial foods. The kidneys also take a hard hit from many toxins to which the body is exposed. Many conventional medications, notably nonsteroidal anti-inflammatories and certain antibiotics, are very damaging to the kidneys. Ultimately, there is not much known about the long-term effects of many food additives and preservatives; fluoride in the drinking water; and all the pesticides and herbicides used in, on and around our companion animals (and ourselves!). Item number three on the list above is a term used by homeopaths to describe a chronic disturbance in the body's function that results in symptoms. Diet in controlling Chronic Renal Failure (CRF)
When I am confronted with a dog or cat who has been diagnosed with chronic renal (kidney) failure (CRF), I generally begin by educating the animal's guardian about the dangers of commercial foods and the benefits of fresh-food feeding. Conventional veterinarians are under the misunderstanding that low protein diets are the best way to feed an animal with chronic renal failure. My experience is that such an approach will lead to the death of the animal in a few months (thus bringing their prognosis to fruition). I have found that just the opposite approach is the most effective for most animals. I suggest feeding a high protein, raw-meat-based diet. I have seen dramatic reductions in elevated kidney blood tests within two weeks in some patients. Why does conventional medicine do the opposite? Because all of the conventional nutrition research is done with processed foods. I haven't seen any done with raw foods. I believe this is the reason for the research data. Heat-treated animal protein, as found in commercial foods, is more difficult to digest. This results in more protein (nitrogen) waste, which the kidneys must remove from the bloodstream. Blood urea nitrogen (BUN) is a protein waste that is measured in a blood test. Therefore, a diet that has high levels of cooked protein is more stressful to the kidneys and results in higher toxicity (BUN) in the blood if the kidneys are not functioning well. Raw protein, in comparison, digests more completely with less waste. This results in more protein for healing and rebuilding tissue without the renal stress. Remember, by nature carnivores eat a very high protein diet. They should have the ability to handle it. Another benefit of the raw foods is that they contain much more water than dry foods. This helps the kidneys discharge waste material. I would not be writing this information if I had not seen many animals improve on such a regimen. Other holistic vets are having the same results." read more Diet in controlling Chronic Renal Failure (CRF)
In the past, it was believed that a low protein diet was essential in controlling Chronic Renal Failure (CRF). The idea behind this is to cut down on the kidneys' load. However, studies done on dogs in renal failure, show that a low protein diet did not help the GFR or BUN of said dogs. Since cats have an even higher protein requirement than dogs, it seems unlikely that they could thrive on low protein diets. As an obligate carnivore, they need the nutrients only available from meat. So one has to walk a fine line between making sure all the kitty's nutritional needs are met, and keeping the stress on the kidneys as low as possible. more info
I would suggest that with the kidney problem you need not use nearly as much silver as would be the case for cancer. A couple of tablespoons to an ounce a day in the water would be fine.
I agree with JAB about getting a home silver generator and we both like the Silver Pupply a lot. But if it were me, I would start off with vastly superior quality Colloidal Silver from CureZone sponsor Utopia Silver - and first time buyers can take advantage of a buy-one, get-one special so that each two bottles only costs about $25 - and then go to the home silver, and the Silver Puppy does make quite good silver.
