But even though some people may pick what people know as a carnivore, they're fursona might not be one.
In real life, I don't eat a lot of "real" meat. Generally it's just bologna, hotdogs, and Burger King chicken tenders; though when I was younger, I liked plain chicken (unlike now where it needs to have breading and seasoning) and turkey, and actually a lot bigger variety of food than I do now. So my main fursona is like me, an omnivore, even though it's a wolf (which are for the most part carnivores, unless you count them eating grass).
Also, a couple of my other fursonas are herbivores or omnivores (the monkey, which eats mainly fruit and maybe some leaves, and the gargoyle/bat, which is a combo of a fruit bat and a vampire bat). Others probably could be but I don't have their diets completely figured out yet.
And I do agree with Zeph that (in general), males go for masculine animals. Though some guys like cute animals, I do know that.
With me, I've always loved all animals and thought that all animals are cute, no matter what (although naked mole rats are a little difficult for me, Rufus from Kim Possible is cute but real ones are kind of weird); some might say I think that way because I'm a female, which wouldn't offend me in any way. So when I picked I chose animals that I love AND that I share characteristics with. No matter what I chose, I knew it'd be cute to me (I mean, come on, one of mine is a Wookie which most people probably wouldn't think of as cute. I love Chewbacca and love making the noise he does, etc., so that's part of why I picked that.).
And I don't think that having more 'ores would help anything. I don't think there could be more anyway. I can't think of anything besides meat-eating, non-meat-eating, and a combination of the two. Maybe there could be other ones but I don't really see how.
