I swear by silver. Being allergic to almost every antibiotic, I had to find something I could take. I was skeptical at first until I tried it. Now, I make sure we are NEVER without a bottle in the house. You're right...it is great for animals too. I use it with my dog. If I think she might need it, I put it down for her. I've noticed, if she really doesn't need it, she won't lap it up, but if she does, she licks the dish like crazy.
