@Chi: Haha, who cares about the homework as long as there are cute kitties around?
The second series is out just now, it's called "Chi's new address". I don't think it's been translated into English yet, but it's fairly easy to understand what's going on even if you have very brief knowledge of Japanese. Especially when you've watched the whole other series before, the patterns of conversations haven't changed much
The only downside is the new opening song. Not convinced... It's not as catchy as the other one.
