Why did they cancel the TV show Fruits Basket?

It wasn't exactly canceled. They just wanted to end the series that way. They change it up though. For instance, what happens in the last episode, is what happens in the beginning of the 6th manga. Which, the anime changed up. The charachters you meet in the 8th manga, were put before the end of the anime. But you really should read the mangas. They also changed up the anime, like Akito is really a woman and she reveals that in the end of the manga. Where in the anime he is a man, and was to die young. Lots of other stuff too, but you should read the manga. (by the way, Tohru's eyes should really be brown)

^they wanted u to think who liks who haha (Kyo+tohru or Yuki+tohru)
