Regardless of which room we're in one of the cats will go into an empty one and then start meowing over & over. It's like a "I'm lonely" meow but we're all in some other room (e.g. living room) and he could come and see everyone. In fact, in some cases he was already sitting in the same room with everyone else before he gets up & goes into another one and starts. I don't understand you, cat.
