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.

"When you meditate, don't send your mind outside. Don't fasten onto any knowledge at all. Whatever knowledge you've gained from books or teachers, don't bring it in to complicate things. Cut away all preoccupations, and then as you meditate let all your knowledge come from what's going on in the mind. When the mind is quiet, you'll know it for yourself. But you have to keep meditating a lot. When the time comes for things to develop, they'll develop on their own. Whatever you know, have it come from your own mind.http://www.accesstoinsight.org/lib/thai ... eleft.html
