Chi is the main character of Chi's Sweet Home, a manga series that began in 2004. Chi is the first cat the Yamadas have cared for, and the mom and dad are bewildered by her toilet training and at a loss over how to deal with her tricks. The manga, which carefully paints a picture of little events in daily life, is very popular. A TV anime version has been airing since March 2008. Each episode runs for about five minutes, so it's only a very short show, but each episode depicts one of the experiences Chi has gone through, and the program has won many fans.
