Thanks for all the comforting words. I am worried and assuming the worst.
I heard back from the vet the the 24 prelim report which is negative which I sort of felt it might me. I have been reading on the subject and from what I gather, it sounds like a lower UTI since there is no blood in actually in the urine, just drops from his peeper after he is done and because the specimen was taken directly from the bladder is why nothing is growing.
He does have a decrease in appetite which is a side effect of the Clavamox, but he did pass the "treat test" and is very vocal so I think he is fine. This is only the 2nd full day of a 2 week course of the antibiodic so I think it is too early to tell.
Thanks for helping this newbie out

I really appreciate it.
