If you generate eye tracking in CATS, the LeftEye and RightEye bones should be pointing straight up, same with the head bone.
The original Eye_L and Eye_R bones probably won't be pointing up, but those can be ignored. Just make sure you use LeftEye and RightEye in Unity.

If by chance the Left/RightEye bones are not pointing straight up, just rotate them in edit mode by grabbing the tail end of the bone (or editing the X/Y values directly).
