Colloidal silver drops, which is not expensive, can cure eye infections and can be purchased online or at a vitamin store. It it used in hospitals to cure eye infections in newborn babies. It is used full strength in the eye but make sure it does not have anything added to it. I currently have a kitten with an eye infection. I did bring the kitten to the vet and received antibiotic drops for the eye and liquid antibiotics to be taken by mouth. The vet bill was $95. If I could not afford the vet, I would use the colloidal silver without the antibiotics. I gave the kitten goat yogurt to restore the friendly flora killed off by the antibiotics. The kitten is 4 weeks old and being nursed by his mother who was a stray that I took in just before the birth. I also would like to respond to froggy 7. Before vets, people used herbs and other alternative remedies. Ancient people had very good medicine that is still used today. I have cured myself and friends of many aliments with herbs and other ancient remedies. If you have ever read All Creatures Great and Small you would see that the farmers had many remedies for their animals that in many cases was just as good or better than what the vet had to offer.
