I wouldn't give it to her if she's not showing any symptoms. You don't want to give them needlessly. Did you get the Little Noses drops? That should help with their congestion and try warming up wet food just a bit to enhance the aroma. I also add plain meat baby food to my kitties' food when they're sick as they seem to respond well to that. I water down their regular food/baby food mixture with plain baby pedialyte to help with electrolytes and hydration.
