It's good that his appetite is improving, even if just a bit!

Yes, you expect right -- I suggest finishing the 2nd cycle of MII. If there's improvement in the next few days, you may want to do a 3rd (this is safe). I suppose you could add Maracyn I to the mix to make it a broad spectrum antibiotic.

You could continue RI+ if you feel he's improved, or you could stop it. It's safe to do for up to 14 days (even then, it's not harmful to go over 14 days, it's just that by that amount of time if parasites were involved, they'd be dead).
