SHEFFIELD LAKE, Ohio -- Authorities say firefighters have rescued an Ohio woman after a boa constrictor wrapped around her neck and began biting her face.

The unnamed 45-year-old Sheffield Lake woman called 911 Thursday afternoon asking for help. The boa constrictor was one of two snakes she'd rescued the day before, the Elyria Chronicle-Telegram reported.

Firefighters found the woman lying in the driveway of her home with the snake wrapped around her neck and biting her. A firefighter used a pocketknife to cut off the snake's head.

The woman was taken to a hospital for apparent non-life threatening injuries.

The woman had 11 snakes, including nine ball pythons and the boa constrictors.

Sheffield Lake is about 25 miles west of Cleveland in Lorain County.
