Given that cheetah claws and antlers would imply a hybrid, we've already been told that doesn't happen except wherein Humans are involved. If a human is a hybrid, it seems they get no visible traits. If two Faunus of different animals conceive offspring, the child will have traits from one but never both of the parents. It is a weird and seemingly arbitrary rule, but them's the brakes.
