Tora

a is the cat owned by the daimyo's wife and it constantly runs away. One of Team 7 first D-Rank missions was to catch Tora after she ran away. Tora also appears in Naruto: Shippūden where Team Ebisu in another D-Rank mission. Both times, Tora is recognized by a red ribbon on its right ear.

As stated by Moegi, the reason for taking so long with the mission was that cat seemed to be used to running away.
