Yep, and because it works out just fine for the cat if Shion comes over, it'll playfully chase the three mice through the whole flat, leaving a mess behind and aggravating Nezumi when in reality it has some kind of agreement with them: You don't eat us and we help you getting Shion over more often. (Because if there are super intelligent mice, Nezumi just has enough bad luck to find a genius cat xD)
