Chi is a michievous newborn kitten who on a leisurely stroll with her family finds herself lost and alone. Seperated from the warmth and protection of her mother, desperately attempts to reunite with her family of feral cats. When the kitten feels all hope is lost, she is found in a park by a young boy named Yohei and his mother. After taking a tumble Yohei feels just as distraught as the kitten he sees before him, and he quickly takes comfort in feeling a sense of sympathy with the cat. And before she could even know what hit her, the little kitty was picked up and soon under the protection and care of Yohei's family--the Yamada's. Every moment of their daily life is filled with something we can all cherish.
In the fourth volume of Chi's Sweet Home, Youhei's actions at the end of volume three has 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 nosey managers and mean hungry bully cats.
But moving alone will be something of an adventure for Chi. While the Yamada's can handle changing their environment now and then, for a kitten their home means much more than just a place to sleep in. When the old apartment starts to disappear, suddenly Chi starts losing all of her favorite toys and her naps spots. She knows they should be in specific places, the smell is still there, but her nappy spot is gone and so are her favorite scratching areas. 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?!?
