Katt

We normally think of Cat and Kat as girls names -- nicknames, essentially, for Catherine and Katherine. But actor Katt Williams, Emmy-nominated for his role in Atlanta, presents the intriguing possibility of it working for a boy as well. He was originally born Micah, and so far, U.S. parents haven't shown much love for Katt as a whole name -- but with unique unisex names drawn from nature on the rise, we wouldn't be surprised to see it catch on.

Pronounced KAT.
