Tora

a is the cat owned by Madam Shijimi, the wife of the Fire Daimyo. Tora constantly runs away. One of Team 7's first D-Rank missions was to catch Tora after she ran away. Tora also appears in Naruto: Shippūden where Team Ebisu were in a D-Rank mission as well. Tora is recognized both times by the 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.
