Cloning is so technically difficult (every species is different !) and so expensive that it will remain an unrealistic technique for decades. For now, the only endangered animals were very close relatives of the domestic horse, cow and goat (not sure abut the last one).
Only in Hollywood movies a single scientist takes a couple of test tubes and in few years has lots of animals of different species!
