Scarlette and Padfoot, thanks for your replies. First of all, Scarlette, please don't be sorry. Any and all help is greatly appreciated. I'm new here and haven't even introduced myself or my animals properly...so I'm just glad someone responded!
Padfoot, I would never use prescription antibiotics without a vets approval. Zymox doesn't contain any antibiotics at all. It's just a matter of me trying to find a non-clinical/non-mail-order source. Nevertheless, everything you mentioned is important to keep in mind. Bacteria, fungi, and viruses all require different treatments and a thorough analysis to see "what's what" (identification of pathogen) should always be a primary concern when trying to diagnose a problem. So thanks for making that point. Anyway, I'm really glad to find an on-line community as helpful as this one. This is a great place to learn new things and "meet" new people. I hope to "talk" again soon. <-Steve->
