Is colloidal silver effective for a stray cat's ear infection?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered

I am treating a stray cat for a bacterial infection (ear) and post surgery from a recent TNVR program, and whatever else he may have from being an outdoor cat with SILVER. Right now, I am giving him 5-6 drops of 30 ppm everyday, and have been for about 5 days. He is a larger cat. Is this enough dosage, and how long should I continue treatment? I only see him at night. Thank you!

Silver can be useful for clearing up skin issues, but I haven't use it alone to deal with ear infections. Ear infections need topical (in the ear) antibiotics to clear up. It's not clear from your question if you're giving the silver orally or topically. I am not aware of an oral use for silver. Unfortunately, it's really hard to clear up ear infections without being able to take a cat to the veterinarian. If possible, I would recommend catching him (in a trap if needed) at night and taking him to the clinic the next morning. There are long lasting ear medication that could work better in this situation. I would recommending asking your vet ahead of time if they carry one of those long lasting options in case he needs it. Other possibilities include a foreign body or ear mites. Good luck! I hope he's feeling better soon!
