2. Cat Girl's [This One's For Taokaka and Neferpitou, Who Is Actually Gender Ambiguous, But I've Always Seen Him/Her As Female]
It is apparently ambiguous, but it's merely another trap by Togashi which he has done in both Hakusho and HxH repeatedly. The anime says one thing but in the actual manga Pitou is a dude. There's even a manga panel on a garment-less Pitou and there are no boobs. I believe Pitou was referred to as a male in a HxH handbook as well.
I thought the same thing about Kalluto
Turns out all the Zoaldyk children are boys. Sigh.
