My pet sitter who comes everyday to walk/feed and take care of Grissom who's 11 weeks old while I'm at work has mentioned something interesting to me. She said that when she is there he is active and alert, but he walks around and whines. He doesn't need to go out, just whines and then plays with a toy, then walks around and whines, finds another toy etc. He'll play with her too, but then whines. I have NEVER heard him whine before other than when he wants to go out and then he does his business and he's perfectly fine. He's not a whiner at all. What do you think this means?
