Up until last Fall, I’d only used colloidal silver randomly for small things on my crew like eye injuries, ear infections, and on Abby’s incisions after her lipoma surgeries. I had, however, seen enough, read enough, and used it on enough things around the house to know it was one of those things I’d be keeping on hand for the next time someone in the house had anything wrong with them. Little did I know my need would be sooner rather than later with a very sick cat.
