Chi's Sweet Home is a series of brief five-minute episodes, taken from a manga which tells the story of a lost kitten (Chi, obviously), who is discovered and taken in by a family.
The animation is pretty basic, but given the fact that the content features a cute kitten, the opening episode can be summed up in just a single word - Awwwwwwwwww.
It's safe to say that the sole purpose of this series is to bring the word 'kawaii' to your lips, and to be fair, the first episode succeeds in that. Yes, it's no deep magnum opus or fantastic psychological study, but it's about a kitten, what more do you want?!
