I'd say it would be unfair if you had failed because of this, since I don't think anyone had any idea this could happen and there was nothing you could do. I hope you do get to continue! A simple matter would be that Spouses/Mortals should avoid becoming friends with Pets. In my Dynasty I only have a few days of a Spouse left before she dies and she is reasonably high relationship with a Cat, I'll ask Metro if he'd like me to try it and see what happens?
