A relative of Angelina K. Barnes returned to her home in Oklahoma City and found the woman wearing a long coat, with her face covered in blood -- later determined to be cat's blood -- ready to attend the concert, KFOR reported.
The light switches in the house had been covered in duct tape to make them almost impossible to turn on.
It was later determined the cat had been drowned in the bathroom, before being sliced open and its eyes mutilated.
The liver of the animal was found in a makeup case on the bathroom's vanity.
Police said Barnes was taken to Griffin Memorial Hospital where she was receiving treatment. She did not attend the Lady Gaga concert.
Although Barnes was diagnosed with depression, neighbors said the violence was "completely out of character."

The court verdict against the National Democratic Party appeared to signal that the Egypt's ruling military was trying to move more swiftly to meet protester demands. It came only days after the ousted Mubarak and his sons were put under detention for interrogation on allegations of corruption and responsibility for the killings of protesters by police.
The protest movement had been pushing for both steps for weeks, with little response from the Armed Forces' Supreme Council, the body of top generals that has held power since Mubarak's Feb. 11 fall. In the meantime, tensions grew between the council and the protesters, some of whom accused the generals of protecting the former president.
The tensions peaked a week ago, when troops attacked protesters massed in Cairo's central Tahrir Square in a pre-dawn raid, killing at least one.

According to the Detroit News, a 56-year-old woman faces multiple felony charges and is being held on $500,000 bond after a 10-hour standoff with police, claiming she was protecting her 13-year-old daughter from unnecessary medication. The story which led to this incident, as reported in the Detroit News and The Voice of Detroit, is quite disturbing.
Maryanne Godboldo's daughter was born with a defective foot that required amputation of her leg below the knee, which led to Maryanne becoming a stay-at-home mother after her birth. Maryanne and her sister Penny now run a dance school in Detroit. Penny Godboldo reported in the Detroit News her niece's confidence grew, and despite her handicap, she swam, sang, danced and played the piano. However, as she approached middle school age, she apparently wanted to start attending school, and therefore had to "catch up" on required immunizations.
As the Detroit News reports:
"We believe she had an adverse reaction to her immunizations," Penny Godboldo said.
"She began acting out of character, being irritated, having facial grimaces that have been associated with immunizations."
Evans said Maryanne Godboldo sought help for her daughter from The Children's Center, an organization that helps families with at-risk children, where a medical and mental health treatment plan was developed. Godboldo told relatives the medications ordered by the doctor worsened symptoms, including behavioral problems.
"It is an undiagnosed condition, but the doctor had given her psychotropic drugs that caused a bad reaction, made things worse," said the girl's father, Mubuarak Hakim. "Maryanne's decision to wean her from that was making a difference, making her better, helping her to be a happy kid again."
Administrators at Brooklyn Academy High School in Bedford-Stuyvesant canceled Friday's talent show in the wake of a all-girl gang assault on one of the student contestants, PIX 11 has learned.
According to authorities, 17-year-old Shacara McLaurin was brutally attacked by at least five other students on April 1st, one of them hitting her in the face with a padlock wrapped in a sock.
"Yo, b--ch, I got a lock," one of the teen suspects allegedly shouted, as she pummeled McLaurin with the weapon.
"I wasn't able to open my jaw. I wasn't able to talk. I wasn't able to sing," the victim told the New York Daily News.
One of McLaurin's fellow classmates, Jacky Alcine, told PIX 11 he had heard McLaurin rehearse for the talent show and knew she was a favorite to win.
"She has a great voice," he said. "It fills the room."

Shannon Johnson was playing a game on Facebook while her 13-month-old son drowned in a full bathtub. She was sentenced Friday to 10 years in prison.
Shannon Johnson, 34, of Fort Lupton, cried as District Judge Thomas Quammen told her he didn't think she was a bad person or that she killed her son on purpose, the Greeley Tribune reported.
But, he added, that doesn't mean her action wasn't criminal.
"You left this little boy in a bathtub so you could entertain yourself on the computer by playing games," Quammen said. "And you left that 13-month-old human being, little Joseph, incredibly for those reasons."
Johnson pleaded guilty in March to negligently causing the death of her child. The charge carried a sentencing range of four to 12 years, but it also left open the possibility she could receive community service or probation. Authorities rejected both of those options, saying they didn't want to play down the seriousness of her crime.
A police officer was helping supervise the lunch period on Tuesday, because both the principal and assistant principal were in a meeting, and the boy got into a confrontation with a school staff member.
