1.Rat:Yuki Sohma is the rat of the Chinese Zodiac. Known to his classmates as 'Prince Yuki', 'Prince Yuki Sohma', or 'Prince Charming', Yuki is seen by others as a beautiful being. Yuki, however, is incredibly insecure. He hates his girly looks, does not know how to interact with other people, and constantly feels insignificant. In spite of this, Yuki maintains a calm, collected attitude most of the time, rarely becoming mad or upset. He is very formal and kind in how he speaks to those around him.
2.Cat:Kyo Sohma is cursed by the spirit of the cat of the zodiac. His full name is Kyonkichi. He transforms into an orange cat whenever he is hugged by a member of the opposite gender or if he is under a great deal of stress. The cat is not an animal in the Chinese Zodiac, but legend has it that the cat may have been included had the rat not tricked it. This may be the reason that he and Yuki Sohma (the rat) do not get along well. However, it is said that Kyo had made a deal with Akito Sohma that if he could beat Yuki, he would not be confined to the Cat's Room.
3.Dog:Shigure Sohma (草摩 紫呉 Sōma Shigure) is the Dog of the Zodiac. He transforms into the Dog of the Chinese Zodiac whenever he is hugged by the opposite gender or his body comes under a great deal of stress. Shigure is the eldest member of the Zodiac. He is the first Sohma to appear in the anime/manga.
4.Boar:Kagura Sohma is the Boar of the Chinese Zodiac. She suggests that Kyo is her fiancee', and that when she and he were young, he asked her to marry him. Kyo argues that it was only because she threatened him. Kagura is in an one-sided love relationship with Kyo and is stubborn to realize that Kyo doesn't love her the way she does towards him.
5.Rabbit:Momiji Sohma (草摩 紅葉, Sōma Momiji) is the rabbit of the Chinese Zodiac. When he first appears in Fruits Basket, he is about to enter 10th grade, and towards the end of the series he is entering his third and final year of his time at Kaibara High.
Momiji appears to be the most child-like in the series, easily mistaken as a middle school student when he was really about to enter high school.
6.Sea horse/Dragon:Hatori Sohma is the Sohma family's personal doctor. He is the only known living Sohma family member with the ability to use the 'memory suppression' technique (a form of hypnosis used by the Sohmas to suppress the memories of those who discover their curse). Hatori is also the dragon/seahorse of the Chinese zodiac.
7.Cow:Hatsuharu "Haru" Sohma is the cow in the Zodiac. He is one year younger than Yuki, Kyo and Tohru. He is currently attending the same high school as Yuki, Kyo, Tohru and Momiji. He was constantly made fun of because of his natural black and white hair due to the influence of the Cow spirit that possesses him.
8.Snake:Ayame Sohma (草摩 綾女, Sōma Ayame) is the biological older brother of Yuki Sohma. He is possessed by the Snake of the Zodiac. Ayame is best friends with Hatori Sohma and Shigure Sohma, and the three of them make up the Mabudachi Trio. Unlike his brother, Ayame is rather loud and flamboyant.
9.Monkey:Ritsu Sohma (草摩 利津 Sōma Ritsu) is the Monkey of the Zodiac. Extremely apologetic, he takes after his mother, the hostess of the Sohma family's onsen, whose position he is in training to take over. Most Sohmas call him "Ri-chan" and, to Shigure's amusement, Tohru calls him "Ri-chan-san". He debuts in Chapter 45. He cross-dresses to ease his nerves.
10.Tiger:Kisa Sohma is the Zodiac representative for the Tiger. She is initially shy and reserved, but began opening up to others when Tohru Honda consoled her.
11.Ram:Hiro Sohma is the Ram of the Zodiac. He is 13-15 years old and is in middle school, along with Kisa Sohma. He is exceedingly good at making sarcastic comments and complaining, but will get very shy and timid once around Kisa. He dislikes Momiji Sohma's hyper and carefree disposition.
12.Horse:Isuzu "Rin" Sohma (草摩 依鈴, Sōma Isuzu) is an only child and a member of the Sohma clan in the manga, transforming into the horse of the Chinese Zodiac. She never appears in the anime.
Her nickname is 'Rin', because 'suzu' translates to 'small bell' in Japanese, and 'rin' resembles the sound a small bell makes. 'Isuzu' is also a rare name. When written as two Kanji characters, it means 'Dependable Bell', which many consider to represent Isuzu's personality and appearance quite well.
13.Rooster:Kureno Sohma is the former rooster of the zodiac whose curse had been broken when he was around Tohru Honda's age. Despite being freed, he said he missed being able to fly, as he usually transformed into a sparrow. He doesn't appear in the anime. He debuts in chapter 50.
So, that makes me year of the Dog and Shigure and I love him :D
