Yes Remy absolutely does!
Whether is potty time, play time, or just "pay attention to me" he most definitely communicates
For "pay attention to me" he is on my desk at work, sitting looking at me, and he picks up his right paw and reaches out for me. He can't quite touch me because of the distance. If I don't reach over to pet him, he adds in a little whine...for effect. It's hilarious
