Chi's Sweet Home Vol 4

Youhei's actions at the end of volume three have motivated his parents to look for a new home for their kids. Chi is moving to a new address; someplace where cats can play to their heart's content without having to worry about nosy managers and mean hungry bully cats. Moving alone will be something of an adventure for Chi. While the Yamadas can handle changing their environment now and then, for a kitten home means much more than just a place to sleep. When the old apartment starts to disappear, suddenly Chi starts losing all of her favorite toys and nap spots. And what are all those boxy things? Why are they all stacked so high up? And what's up with all the noise around them? Are there dogs behind all of this?!?
