Federal investigators cleared Disney in the deaths of a dozen exotic animals at its new wildlife theme park.

The Department of Agriculture said Wednesday it found no violations of the Animal Welfare Act in a three-week investigation of Walt Disney World's 500-acre Animal Kingdom.The park, which opened for the first time Wednesday to thousands of customers, could have had its license revoked and faced fines of $2,500 a day.

Since September, four cheetah cubs, two rhinos, two hippos and four other creatures have died at or en route to the $800 million Animal Kingdom.
