Ohio's state veterinarian says testing of a half-dozen exotic animals that survived release after their owner killed himself won't begin for several weeks.
Dr. Tony Forshey said Monday the animals must be anesthetized to have blood drawn. He's worried they're too weak to survive the procedure.
The Columbus zoo is caring for three leopards, two monkeys and a young grizzly bear taken from a Zanesville home two weeks ago after owner Terry Thompson freed dozens of animals, then shot himself.
Police were forced to kill 48 animals, including lions, bears and 18 endangered Bengal tigers.
An email seeking comment was sent Monday to an attorney for the owner's widow, Marian Thompson, who had sought to reclaim the animals. Both she and her attorney have repeatedly declined comment.
