Mini is a very feisty cat. She is very short tempered, and when angry, will unleash rude comments. The dogs in Guru's gang have learned not to cross her. Even though she seems unapproachable at some points she really has a soft heart for those she cares about and would risk everything for their well being. She's one of the heroines of the movie.
She treats everyone in Guru's gang like they're her brothers. She wishes she could be a dog and has a minor crush on Romeo, as shown in the middle of the movie. Even though she doesn't show it, she cares a lot about her friends and has a good heart.
