It's about time! We've had Optimus for almost a month now. Over the past 2 days he's only peed in the house once, and it was my fault (Hilliary was at class and I was focused on fixing her computer [stupid Vista...]). He's actually been a very good boy the last 2 days too. His biting has gone down quite a bit as well. We're really not doing anything different, I think he's just finally starting to learn! We're so proud of him!

On a separate note, as of yesterday, his second ear is now fully standing up!
