Tora

is the cat owned by Madam Shijimi, the wife of the Fire Daimyō.

Despite, or better yet, because of the huge amount of affection Madam Shijimi shows to it, which includes nearly squeezing the life out of the cat, Tora constantly tries to run away, leading a Konoha genin team to be sent to find her. Team Kakashi and Team Ebisu have both had the privilege of looking for her, each time taking longer than the last as Tora gets better at hiding.

Appearance
Tora is recognised both times by the red ribbon on its right ear.

Trivia

 * Tora means "tiger".
 * In episode 6, in the original Naruto series, Tora had a line running down its forehead with three lines going across it, but in Naruto Shippūden, it doesn't appear.
