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

No medicine chest should be without colloidal silver

Colloidal Silver is an amazing product with many good qualities as a natural medicine for cats -- dogs & humans too!  Cat rescues could save a lot of money by using Colloidal Silver in place of trips to the veterinarians and using messy, bad tasting antibiotics*. Many holistic animal practitioners and veterinarians use Colloidal Silver for their patients. 

Colloidal Silver touts these benefits:

  • non-toxic, will not damage organs
  • no side effects when used as directed
  • works as a very effective 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 (dab on with a cotton square)
  • nearly tasteless and odorless

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

Cats with FeLV, FIV, or any other immune system dysfunction are at a higher risk for other bacterial and viral infections.  Colloidal Silver can be used as a daily immune preventative/protectant. According to the EPA, a human may safely ingest 178,850 servings of Sovereign Silver over a 70-year period.  As the EPA does not test the product on cats, this is just a comparison as to its safety with daily use.  Personally, I don't like to use the same product every single day forever.  I believe (as do many holistic animal practitioners) that it is best to cycle supplements. This way, 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, I use it for three weeks on, and one week off. This is a typical regimen given by holistic practitioners and some supplement companies for long-term use of a natural supplement.

Colloidal Silver can be added to cat 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, as it will not burn the eyes.

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

Anytime I get a bit run down from too little sleep, I will start to get a sore throat.  I squirt two full droppers 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 brand - Sovereign Silver

*Disclaimer: This post contains an affiliate link, which means I receive a very small commission if you purchase through links I provide (at no extra cost to you). It is a great way to say thanks if you find my information helpful for you and your cat. I personally use or have used any products I recommend. 

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.  On the contrary, some brands contain salts, proteins, compounds or stabilizers, and they 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. This is an industry low amongst competitors.  With this low particle size, its 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:  buy colloidal silver

*I am not a veterinarian nor am I prescribing colloidal silver in place of antibiotics in cats who are extremely ill . 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 🙂

      You’re welcome Elizabeth. I cannot give enough praise to colloidal silver.

    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).

    Thank you

      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. You can watch my Healthy Cats Detox videos to help your cat have a healthier immune system here:

    Dear Kat, hello and thank you for helping rescue animals! I totally understand because I have volunteered at an animal rescue where I worked in the on-site “cat hospital.” It’s really tough to treat them with so many together. Some will improve, then more sick ones are exposed to the improving ones, and it just keeps passing around. In my opinion and experience, using Colloidal Silver alone won’t help a cat recover from a URI. There are many factors playing into building the immune system, with quality of food being a major player. No doubt, rescues struggle with funding, and using the best quality food is usually out of the question. If at all possible, at least avoid dry food that contains corn, soy, wheat and artificial colors. Those are your biggest offenders–the lowest quality ingredients that weaken the immune system. Administering Colloidal Silver two times per day should be enough to help. Is it possible to serve a little dollop of wet food on top of the meal of dry food? The Colloidal Silver does not need to be mixed in, this is just more work for the staff. Just dropper it right onto the wet or even just the dry food. Are the cats all together eating out of the same large platters of dry food or are they separated with individual meals? Because if they are all together, of course, it’s impossible to know who is getting how much, if any, Colloidal Silver.

    They need something else to help strengthen the immune system. I have used classical (single remedy) homeopathy with great success. However, it is very specific to individual symptoms. What works for one may not work for the other cat. Holistic Animal Medicines is an on-line supplier in Australia of homeopathic formulas, including formulas for URI in cats. They have changed their website since I last ordered a few years ago. They used to offer individual formulas rather than having to buy the whole set. You could email them and explain the situation that it would be difficult to administer all the items in the set to so many cats. They may sell you just the #1 Virus Respiratory item. When I worked at the rescue, Holistic Animal Medicines instructed me to add drops of one of their infection fighter products (I don’t recall which one) into a spray bottle of distilled water, and spray the water and dry food platters two times per day. This was for 200 cats! If the bottle didn’t get used quickly enough though, mold could start growing in it. The spray bottles needed to be kept in the fridge to help prevent mold from growing as quickly. The rescue owner and volunteers said they saw improvement in the cats. In the “cat hospital” of 20-30 cats, I wrote instructions on cat’s medical care clipboards for the other volunteers to administer two times per day. Some people did it if they remembered, but it was better than nothing.

    The other thing I have used for URI is electrolytes, as most cats with a URI are losing them in their bodily fluid excretions, further weakening them. I used Bounce Back, which is in powder form and mixed with water in small batches when you need it. It is nearly tasteless and odorless like the CS.

    To answer your question about serving CS in stainless steel bowls, I never heard of that being a problem. The CS will be on the food only a short period of time. And again, just dropper it on top of the food, rather than mixing in where it would have more chance of contact with the bowls. Just make a little well with the spoon in the canned food to hold the CS. They will hopefully lap it right up. Not eating due to the URI? Has to be administered in the mouth and you can wipe their little noses with cotton pad soaked in CS.

    To answer your other question about adding CS to subcutaneous fluids, being I am not a veterinarian, I have no idea about that. I have never come across it or searched for that. Holistic Animal Medicines is big on CS, and I have not seen any mention of using CS in a sub-q manner. I certainly recommend to not administer it intravenously without the instruction of a medical professional who knows how to use it in that manner. All the best to you and the kitties! Please keep me posted. I would love to hear if you see any improvement with any of these suggestions.
