No a cloned animal does not have buddha nature. A cloned animal is buddha nature, just as is everything else that arises from emptiness, including the emptiness itself.
If you state it as a cloned animal having buddha nature you are supposing an independent entity that possesses some thing or quality called buddha-nature. Non-self means non-self all the way down.
EDIT: changed "not-self" to "non-self" because that seems more correct.

"Even if you've read the whole Canon and can remember lots of teachings; even if you can explain them in poignant ways, with lots of people to respect you; even if you build a lot of monastery buildings, or can explain inconstancy, stress, and not-self in the most detailed fashion ... The only thing that serves your own true purpose is release from suffering.
