Hey, no worries! I stay very on-topic on the bug reports side but if they didn't want us to generally discuss Sims 4, then they should not have created a General Discussion area in a Sims 4 forum! xD I usually learn more about the game when things get a little bit OT anyway. Let me know if you ever get a chance to try that relationship.add_bit cheat or if I can re-create the issue in one of my saves then I will give it a go.
P.S. I think the cat's name was Midnight and I was using the Karma Powers in Sims 3 Pets to pretend my Sim was a witch with Midnight as her familiar. Be mean to my Sim and you might find an asteroid falling on your head! xDDD
