Police say when an officer asked an Oklahoma woman why she tried to stab her neighbour, she said: "I had sex with my cat and everyone knows."

According to a police report obtained by the Smoking Gun, the 23-year-old woman allegedly brandished a knife and threatened to kill her elderly neighbour.

The 72-year-old man called police.

The police report says an officer asked the woman why she threatened her neighbour, and she replied: "Because of what he did to me."

When the cop asked what he did, she said: "Because everyone knows. I had sex with my cat and everyone knows."

"This is news to me," the neighbour said.

She later admitted her neighbour had nothing to do with it and she was "just mad because everyone knows."

She has been charged with assault and battery with a deadly weapon.
