Jatt and Jutt are two long-eared owl relatives (possibly brothers or cousins) who serve as supporting antagonists in the Guardians of Ga'Hoole book The Capture and the 2010 film The Legend of The Guardians: The Owls of Ga'Hoole.
Jatt guards St. Aggie's library on the night Soren and Gylfie attempt to escape. Grimble, an owl falsely working at St. Aggie's in order to protect his family, plans to help Soren and Gylfie escape by tricking Jatt into thinking that Jutt accused the battle claw repository's director Tumak of not handling the battle claws right and they began dulling for Tumak's spot. Grimble offers to take Jatt's place as guard while Jatt goes to try and fight for the spot himself. However, when Jatt left, Grimble let Soren and Gylfie escape.
When Soren, Gylfie and fellow Band members Twilight and Digger were in the Desert of Kuneer, Jatt, Jutt and a moon-blinked owl known as 47-2 arrived on patrol and attacked the quartet. However with the help of two bald eagles named Streak and Zan, the Band killed Jatt and Jutt.
Legend of The Guardians: The Owls of Ga'Hoole
In this film, Jatt and Jutt kidnap Soren and his brother Kludd (after saving them from a Tasmanian Devil) and take them to St. Aggie's.
Unlike the book, Jatt and Jutt are not leaders at St. Aggie's but instead capture owlets for them to be either moon-blinked and made into pickers or become soldiers for the Pure Ones. They also observe the owlets being moon-blinked and also observe the pelletorium.
During the Pure Ones battle against the Guardians, both Jatt and Jutt are struck in the face by Twilight's lute.
