How long do most refridgerated meds last? Like Amoxi, Clavamox, Cephalexin, etc... One of the bottles says 14 days, but is that strictly 14 days only? Is it bad after that? Can it still be used? I had a kitten that passed away while on Amoxi and I always used a clean dropper when I gave him his meds so its not contaminated or anything. It has been about a month though. Can I still use it when my other cats get a little cold?
