What other animals have been cloned before China clones monkeys?

Researchers at the Chinese Academy of Sciences Institute of Neuroscience in Shanghai announced on Jan. 24 that they've successfully cloned monkeys for the first time, using the same technique that produced Dolly the sheep two decades ago, offering possibilities for the treatment of some complex human diseases. Scientists worldwide have cloned cows, pigs, dogs, rabbits, and rats one after another over the past two decades, let's take a review.
