he has been diagnosed by a vet, but no, he hasn't had any cultures. I said I was puttig him on Baytril because we had tried Clavamox and that didn't seem to work. If he's not better in a week on Baytril then I will ask my vet to do further testing. Thanks for your concern, but my cats get the best of veterinary care even when I can't afford to bring myself to the doctor. I was asking about homeopathic remedies to help enhance what I'm already doing, i.e., herbs, vitamings, anything to boost his immune system. I'll keep you posted on his progress.
