Since the twolegger is on my mind...

a few quick questions for those of y'all who know kashrut better than I do.

1. I seem to remember that giraffes are considered kosher animals, but I could be wrong. Anyone care to verify or refute this?
2. How about okapi?
3. Monkeys? I am looking for rulings on creatures with grasping ability here, since there is a possibility that our riding animal might have rudimentary talents in that area.
