The U.S. Department of Agriculture is considering adopting new regulations for zoos at the request of People for the Ethical Treatment of Animals (PETA) that would require humane treatment for bears. The proposed rules would mandate the Animal and Plant Health Inspection Service (APHIS) to hire a bear expert, prohibit bear pits, and require rules so bears are not stressed, frustrated, and bored. PETA, which killed 1,792 stray cats and dogs in 2013, first petitioned the USDA to adopt its rules in 2012.
