Melissa, I'm glad to hear that Hermes is now on antibiotics and hopefully he'll recover quickly. I'm so sorry to hear that Apollo is still sick. If he's still on antibiotics, do you think that this is causing him to become sick? My Storm became very sick after he'd been on Clavamox pills for a while and my vet at the time said that some cats will become sick from it. He threw up and another time he had a lot of diarrhea from a different type of antibiotic. He then received a shot for the rest of his doseage and didn't have a reaction to it. Lots of prayers and positive thoughts are being sent to both Apollo and Hermes.
