Well, we all know the egg came first
Many of the stats I've seen for the fandom have said the ratio is about 1:1. The furmeets I've been to have been predominantly female. Several sites I've joined have been biased in membership in favour of women. So I wouldn't say it's male dominated. Just the males are perhaps more vocal and open about being furry?
I will say I've not seen any stats that aren't less than three or four years old, so I'm not up to date XD
Edited to state my point a bit differently.
