The likelyhood of the existence of female preds is quite high, although what they would actually look like is a different story all together. Whether they would even have a "feminine" body is questionable, as breasts are typically used by mammals to feed their young, wheras predators are clearly not mammalian, & their mandibles & sharp teeth would make breast feeding an extreme issue, meaning that it is doubtful that a female pred would actually have a feminine physique.
Males though do have similar features to certain mammals, so it is a slight possibility though that females might be built more as we would imagine them.
