Hey, Weeze, long time no see.

I'm glad to hear you already took her to the vet, it really makes me sad when people post here, their first post, about an obviously ill cat that they have not bothered to take to the vet.

What I would do next is call the vet back up and tell him/her that the condition is persisting. Sometimes something not to worry about becomes something to worry about when it persists.

I have no personal experience with this to add, though. Sorry!

Hope little Tiger gets better!
