Louise
Louise (ルイーズ, Ruiizu) is Telma's cat in Twilight Princess. She is white and fluffy, and is similar in appearance to a Persian cat. Whilst unable to aid Link in his human form, as a cat she proves to be very helpful to Link when he is in his wolf form. She helps Link into the sewers under Castle Town by helping him to the secret entrance in Telma's Bar, and later tells him about how to retrieve the statue from the skeletal dogs who stole it from her (when she had previously stolen it from the doctor's office). Louise is renowned by the other cats in the area for knowing everything that is happening in Castle Town. If Link, in human form, interacts with Louise in Telma's Bar she will happily meow.
She is seen last jumping on the table in Telma's bar during the credits.
