Angelina Barnes was charged with animal cruelty for slaughtering the family moggy in order to make an outfit to wear to one of the star's concerts.
The 15-year-old tabby cat was drowned and its belly slashed. It's eyes were mutilated and its liver was found on a make-up case in the bathroom.
Barnes, 20, from Oklahoma, is now receiving hospital treatment.
She was charged after a relative returned home in Oklahoma City and found the woman wearing a long coat, with her face covered in blood, ready to head to the concert.
The light switches in the house had been covered in duct tape to make them almost impossible to turn on.
Police spokesman Sgt Gary Knight said: "There were things done to the house like covering light switches with duct tape so she wouldn't be able to turn on the light.
"This person's relative became very afraid that the suspect was going to try to do harm to her."
It was later established the cat had been drowned in the bathroom before it was savaged.
Barnes did not attend the concert and although she was diagnosed with depression, neighbours said the violence was "completely out of character".
At hospital she allegedly then threatened a male nurse with a piece of glass.
