Colloidal Silver for Cats

By Tammy Quinn Mckillip

Colloidal silver is a natural and highly effective antimicrobial agent used to treat a variety of ailments, from wounds, burns and skin diseases, to internal parasites, viruses and bacterial infections. It is approved by the FDA as a food supplement and is considered a safe alternative to pharmaceutical medications for use in cats, dogs, horses, humans and other animals.

What is it?

Colloidal silver is created by inserting positively charged, microscopic silver ions into purified water. This is done inserting silver probes that are receiving an electrically charged current into the water. Tiny bits of silver are then transferred into the water in a suspended, positively charged state. When the colloidal silver is ingested, the silver ions rob single celled organisms of developing viruses and bacterium of their ability to produce oxygen--effectively suffocating them. These dead pathogens are then eliminated from the body. Surrounding healthy enzymes and cells are unaffected because the silver only affects single-celled organisms.


Colloidal silver may be used to treat over 650 diseases, ailments and disorders in cats and other animals, including humans. It is an effective anti-microbial agent, anti-parasitic and anti-viral agent. It also is effective in healing digestive disorders, wounds, burns, yeast imbalances, thyroid, liver, kidney, circulation, vision, hearing and other maladies affecting pets and people.


Colloidal silver may be applied as liquid suspension drops directly into the skin, ears, eyes and nose. It may also be ingested in its liquid form or can be made into a paste, salve or cream to be applied to wounds, burns, sores, bites, stings, skin infections or parasite infestations. Another method of ingesting colloidal silver is by putting it onto the cat's food. It may also be injected intravenously.


Silver has been used as a healing and health-promoting agent throughout recorded history. The term "blue blood" refers to the use of silver by royalty, who kept their food in silver containers and ate from silver plates and bowls, using silver utensils. Although they were rarely ill due to the amount of silver in their systems, the silver eventually built up inside of their bloodstreams, causing them to have a blueish tint to their skin and nails. Colloidal silver was commonly used by doctors and farm veterinarians to treat a variety of ailments in humans and pets up until the 1930s, when the price of silver became prohibitive due to market conditions, and the advent of effective pharmaceuticals led to a decrease in its use as an antimicrobial agent. As "traditional" medicine was pushed into the background, the use of colloidal silver continued as an "alternative" medical practice for pets and humans.


Although colloidal silver is approved by the FDA for use as a nutritional supplement, it is NOT currently approved for medical use. The FDA does not allow the makers of colloidal silver supplements to make claims about the products effectiveness against any medical condition on packaging or in literature about the products. The only adverse medical condition known to be caused by chronic use of colloidal silver is argyria--a darkening of the skin pigmentation which creates a blue or gray coloration in humans using colloidal silver at extremely high concentrations for a long period of time. Other potential toxic effects from using massive doses of colloidal silver can include irritability and excitability. Suspended forms of colloidal silver should not produce build-ups of the product inside the body of cats or other animals, as the ions may only attach themselves to single-celled organisms and are eliminated with the pathogens from the body. More concentrated versions of colloidal silver are also available, created using methods other than electro-ionization, and these products are more likely to deliver non-suspended particles of silver into the body, which could produce mild toxicity when used regularly. Always speak to your veterinarian before using colloidal silver or any alternative product to heal or promote the health of your cat.
