I think as a GM you should set rules. I suspected that Artemis and Luna and any cats that would appear to be GM-controlled only. If that's the case, then you simply just need to say that all cats are GM-controlled and that no one is allowed to control them.<br/><br/>If you didn't want characters to leave the U.N. rep, then you should have made that clear. You just need to be assertive with what you want and what you're trying to do. When you leave everyone hanging, it only just gives us the freedom of assumption. Communicate what you want to happen.
