A U.S. woman has been charged with animal cruelty after killing her relative’s cat and using its blood as part of an outfit to wear at a Lady Gaga concert.

Angelina Khristian Barnes, 20, of Edmond, Okla., was charged this week.

Her aunt reported the March incident after discovering her niece with the 15-year-old tabby cat’s blood smeared all over her face at the home they shared.

Barnes was also wearing her winter coat and an outfit the aunt had bought for her for the concert the following week, according to the police report. She was wearing bright red lipstick and black eye makeup, with her hair in pigtails.

The light switches and home’s security alarm were also covered in duct tape and paper towels, the report stated.

Barnes has been diagnosed with depression, but neighbours said the violent act is unlike her, according to reports.

The incident also took the Oklahoma City Police Department by surprise.

“This is pretty strange, pretty unusual,” said Sgt. Gary Knight told the Star.

He confirmed that animal-cruelty cases occur, but nothing like this has ever happened before.

Investigators found the dead cat in the bathroom. It had been drowned and mutilated.

KFOR News reported that Barnes is now receiving treatment at an Oklahoma hospital.
