An Aussie woman has been sentenced to 180 hours of community service for slicing the head off a mouse with a steak knife and posting a video of its 40-second death on Facebook. The 23-year-old woman pleaded guilty to animal cruelty. A second enemy of animals faced charges the same day of torturing and blowing up five possums. He's being held behind bars pending his sentencing later this month, AP reports. (More animal cruelty stories.)
