Colloidal Silver Works as a Natural Antibiotic, Antiviral, and Antifungal

Every feline's natural medicine chest and cat rescue should include colloidal silver

Colloidal Silver is an amazing product with many good qualities as a natural medicine for cats (and dogs & humans too!). Cat rescues could save a lot of their precious donation money by using Colloidal Silver in place of trips to the veterinarians and using messy, bad tasting antibiotics* :

  • non-toxic, will not damage organs
  • no side effects when used as directed
  • works as an antibiotic, anti-viral, and anti-fungal
  • does not kill off friendly gut bacteria, like antibiotics do
  • helps wounds heal faster with oral and external application (by dabbing on with a cotton square)
  • nearly tasteless and odorless, which works well for using with cats (and dogs too!)

These are some conditions I have used it for with cats (mostly rescue and foster cats that were sick):

  • urinary tract infections
  • upper respiratory infections
  • post-surgery
  • Feline Leukemia (FeLV) and Feline Herpes

Colloidal Silver can be added to your cat's food and mixed in.  I have never had a cat turn down their food with Colloidal Silver in or on it.  If your cat is not eating, and you are feeding via a dropper or giving liquid supplements, Colloidal Silver can be added to the mix. For eye infections, it can be used to wipe the eyes clean with a cotton square, and it will not burn the eyes.

You could also use this as a daily immune system protector/preventative for cats with FeLV and FIV, or any other immune system dysfunction, as these cats are at a higher risk for other bacterial and viral infections.  According to the EPA, a human may safely ingest 178,850 servings of this particular brand over a 70-year period.  (The EPA does not test the product on cats, so this is just a comparison as to how safe it is to ingest daily.)  Holistic animal practitioners and veterinarians use and recommend Colloidal Silver.  Personally, I don't like to use the same product every single day forever.  I believe (as do many animal and human holistic practitioners) it is best to cycle supplements so the body does not become accustomed to something and no longer benefit from it.  If you were to use it daily as an immune system protector/preventative, my recommendation is to use it three weeks on, and one week off. This is a typical regimen given by holistic practitioners and some supplement companies for a product being used long-term.

Colloidal Silver is great to have on hand for yourself as well

Anytime I've gotten a bit run down with too little sleep, I will start to get a sore throat.  I squirt two dropper fulls right onto the back of my throat.  This one-time dose almost always stops the sore throat in its tracks.  On occasion, I will need to take a second dose a few hours later. 

My favorite, recommended brand

The brand I recommend and have used for years is Sovereign Silver's Bio-Active Silver Hydrosol.  It contains 98% positively charged silver in pharmaceutical-grade purified water, and nothing else.  Some brands contain salts, proteins, compounds or stabilizers and may or may not claim to contain these ingredients.  These added ingredients affect silver's safety and efficacy. 

A silver's molecular particle size determines the absorption rate by the body.  Sovereign Silver's particle size is highly absorbed at 0.8mm, an industry low.  With this low particle size, it's 10 ppm (parts per million) is more effective than other brands containing up to 500 ppm.  So, don't be fooled by the higher ppm's of other brands.

Where to buy Colloidal Silver

You can buy this at health food stores and on-line supplement stores.  You can also buy it on Amazon for a better price.  Check it out here:  natural antibiotic

If you need personalized support for your cat, please schedule a consultation, and I'll be glad to support you!  Schedule a Thrive Nutrition Program here.

*I am not prescribing colloidal silver in place of antibiotics in extremely ill cases for cat rescues. But simply suggesting to give it a try for common upper respiratory infections and supporting cats with weakened immune systems. You will be pleasantly surprised.

    I’m so glad you wrote this, Kim, as I didn’t really know anything about colloidal silver. It sounds like a great thing to have on hand! And what a bonus that they’ll eat it mixed into their food, too! Such helpful info- thank you 🙂

    I’m curious to know how many drops and how many times daily? Thanks

      Hi Catherine, thanks for visiting my site and reading this article. Since I’m not a doctor/veterinarian, I cannot prescribe dosages. But I can tell you what I do based on what I’ve researched among holistic animal practitioners. It’s really difficult, rather impossible, to overdose or overuse colloidal silver, especially this brand. Using the adult dose on the label as a reference point for oral use, cut amount in half for a child or medium sized dog. Then cut in half again for a cat or small dog. Bringing you to 1/4 the adult dose. I just use a dropper-full from the 4-oz bottle. If I have the 8-oz bottle with the larger dropper, I use 3/4 of a dropper or so.

      Sovereign Silver’s label indicates how many times per day depending on severity of symptoms up to 7 times daily or if you’re using as daily maintenance, once daily. You might get some resistance or hiding cats if trying to use 7 times a day! I have used it 3-4 times per day per holistic animal practitioners & veterinarians. This would include 2 doses going in 2 meals per day and 1-2 doses going in the mouth. If it’s a kitten eating 4 times per day, then there are your 4 doses. To give in the mouth, dropper into corner of mouth on gums and try not to touch dropper to the mouth. You don’t want to squirt it into the back of their throats, as this can make them choke/cough and scares them.

      All the best to you and your cat(s).

      Hi Wendy,

      First, I want to say a big Thank You for taking in and caring for an FIV positive cat. He is very fortunate to have someone to care for him and that his life was not ended in an animal control facility due to having FIV. Cats with FIV can live long lives, as you probably already know. Secondly, I want to apologize for not responding sooner. I had some life stuff going on and not tending to my website for several months. Your question was answered in reply to someone else who had the same question, and it appears just above yours. Please refer to it, and my answer is based on the brand of colloidal silver I use and recommend. But if you use a different brand, you can follow the same guidelines.

      In regards to your cat not being willing to eat canned food, cats can become addicted to dry food and be very resistant to changing over to canned or homemade cooked or raw food. Feeding him canned, homemade cooked or raw food would help him have a stronger immune system and maybe stop getting these recurring colds because dry cat food requires the cat’s system to work harder, it is not fully digested and turns into excess fat, and is not utilized by their bodies to nourish our cats. Getting them to change over requires a lot of tough love and patience! You might consider getting some assistance with changing his diet to one more species appropriate. Be sure to check out my Thrive Nutrition Programs. At the very minimum, be sure to avoid corn, wheat, soy, and by-products in dry foods. Although, I’m not at all hip on the beans and green peas now being used–all of which are not species appropriate protein sources. Those come with another set of problems.

      Finally, there are many variables involved when we are looking at strengthening our cat’s immune systems. Household cleaning products, spray and plug-in air fresheners, laundry products, and even food and water bowls.
