I hate it when people ignore your efforts to contact them - will it kill them to just call back and say "no thanks"? I've had so many people blow me off on free stuff from Craigslist. It's FREE for crying out loud, could they not text me back and say they changed their minds instead of making me waste time rearraging my time to accommodate flakes?

anyways, sorry for that impromptu rant. I thoroughly sympathize with what you're going through. I went through that when I introduced a younger male cat to my older female. He was hit by a car and couldn't see or walk. When I first introduced them, the first thing he did was chase her!! He's since made a remarkable recovery and walks well and definitely isn't blind.

I've also had no luck with feliway myself. Morley is also food obsessed (he topped out at 21lbs at his heaviest). He was literally yeowling and the only thing that would quiet him was food. He was so agitated he would pick on the female, or when my rottie was still alive he would even go after him. As a last resort I had to medicate him. I hated it, but it was seriously to preserve all our sanity (and the safety of the little female and the Morley's life if the dog turned, which I would not have blamed him one bit).

Long and short, he's 13 years old now and much more mellow (he's off meds now). Ironically what really mellowed him out is the third cat. This was my parents' cat that I took in after my mother's vagabond lifestyle started and this cat LOVES cats. Licks and cuddles with Morley like nothing else and that really seems to have calmed him. Though I think age has a lot to do with it, too.

Sorry I'm not offering my advice. I just empathize with you greatly as I know how stressful it is. I hope everything works out for you!
