Dharma:URI - stinky discharge

[Hideyo Yamamoto]

Hi, my Dharma has some stinky discharge from her nose – it had sort of greenish and yellownish color – could this be bacterial or viral?  I read somewhere that if it’s green, it’s viral and if it’s yellow, it’s bacterial – is it the case?  Or it’s hard to tell by the color?   My vet closed for the weekend, and I am not sure which antbiotics to use .. I was going to baytrill, but I remember my vet saying that not to recommended a kitty less than a year or 6 months old and I am a bit nervous using it (I also have a bad experience with it) ..do you have any suggestions?  Has anyone used baytrill on your kittens?  She is already on intereron, predisolone, and started on epogen and don’t want to give too many things, but I also want to help her URI ---any insight is appreciated..
