Cato 1

My first thought is the character from the Hunger Games. Though I personally don't find the character a bad association, there are people in the fandom who dislike the Career tributes (which Cato is a part of) and see the character as a negative association.

I think it's a lovely uncommon name that ought to get used more. I remember it was used in The Hunger Games books, but I'd like to hear it more on actual people.

I'm surprised this isn't more trendy, especially after the Hunger Games.
