I have Baytril that's three years old. It's got a yellowish tint to it, but I can't tell how 'clear' it is due to the container its in. I mention that because of some post someone made about it getting old and becoming 'cloudy'. A vet told me it was okay to use it, through their receptionist. They didn't ask what it looked like. I'm not sure I trust this, but I need to know because if I can use it, I need to use it since the vet isn't avail to get me anything else until monday. Anyone know for sure if this is safe?
