Zoo officials have euthanized a leopard that was among six creatures kept in Columbus since their suicidal owner – Terry Thompson of Kopchak Road – released dozens of exotic animals that were subsequently killed by Muskingum County Sheriff’s Deputies. The Columbus Zoo and the Ohio Department of Agriculture says a keeper was moving the male spotted leopard between enclosures Sunday when the animal unexpectedly reversed course as a door was being lowered. It was struck on the neck. A Zoo veterinarian determined the unresponsive cat suffered a spinal cord injury. The State Veterinarian decided to euthanize it. It had been under state-issue quarantine order with two other leopards, two primates and a bear that survived the October hunt on Thompson’s farm. An attorney for the owner’s widow says he’s withholding comment until he learns more about what happened.
