I think Cathar is a great choice for a new playable species, and glad to see a thread about it here. ^^
I am super curious to see what options will be available for them too! If I can make one with a decent looking head of hair (I'm weird, I can't stand playing bald or near-bald characters, lol) I am totally making myself a kitty when they are released. Definitely saving a class/slot for one! And hopefully they will be unlockable through legacy too, like current species are.
Crossing my fingers for a lioness or snow leopard type of pelt! <3
