What happens to Cat's clones doesn't seem to affect her main body in a lingering manner like an injury would, so they are effectively exact projections of her, just with DNA included. We know this because if you have sex with her, MC comments on how tight she feels and that she seemed in a bit of pain for a moment. Cat explains her real body is a virgin, so every clone she makes is effectively also a virgin. Despite her clones having sex many, many times, none of that has affected her original body at all. So if she's at increased risk of being injured, it'd only be because she might not be able to concentrate as well in her main body movements.
