This is a great product, if it could be packaged for summer weather
So far, have ordered from various sellers (they are the ones who package and send to Amazon).  It's sent in a plastic bubble wrap, and over the summer, it arrives extremely hot (it gets up to 95 or 105 here).  Silver has to stay at around 65 to 70 F, so that the silver doesn't separate from the water and become various bad to the taste and very dangerously unhealthy, please taste before giving to pet!  I've not been able to give this to my pet this summer, sadly, it's also not effective like this.  Normally, it helps if my guinea pig gets an upper respiratory, I can put it in her eyes if she has a bacteria or pink eye.  I also give her around 1/4 t 3 times per day if actively sick or put a little in her water to keep away infection, this is because it's 10ppm (pet strength).  Please don't give this to a baby piggy, I don't know the conversion, maybe if it was a few tiny drops?  She is 2 lbs.  Otherwise, generally, it's an amazing product.  I'm going to write a review about summer packaging to the various sellers.
