aww Stacer I can't imagine what you are going through. I too would be starting to think of other options if my cat was peeing on everything. Cat pee is NOT a pleasant smell!
I don't know much about cats but a few questions popped into my mind
- what is Angus' background? Was he a stray cat before you got him? How old was he when you got him?
- what is his relationship with the other cat in the house??
and hope that you can find a solution soon!
