I'm not sure why I didn't notice this before but for some reason it popped into my head as I was getting up this morning. The last place you want to put a Feliway diffuser is near the litter box! They're supposed to go in areas that you DON'T want a cat to pee. Facial pheromones, which are the happy friendly ones that Feliway mimics, have opposite intentions from the territorial "aggressive" pheromones that are associated with urine and feces. This is why you'll rarely see a cat rubbing its chin on things near the litter box. It could partly be that Angus is now confused by the facial pheromones existing where only butt-end pheromones should be. I would move that diffuser to a location where Angus is currently peeing, like in your bedroom, and I'd also stop putting any on his collar. You want the pheromones to be site specific in this case.
If I think of anything else, I'll let you know.
