(Newser) – UK cops thought they'd found the marijuana mother lode—infrared scanners on a helicopter indicated a large, concentrated use of electricity in a house located in the West Yorkshire town of Odsal. The heat signature screamed pot nursery, but when police arrived, they found the last thing they expected: guinea pigs.



A local elementary-school teacher who lives in the house said she received a call at work. "The police came on the phone and said: 'We think you're growing cannabis in your garage,' she told the BBC. "I said: 'No, it's a heater to keep my guinea pigs warm because it's been so cold.'" Police later apologized for the mix-up. (Read more guinea pig stories.)
