She is not cursed, she is a beastkin: when she joined the group Chilchack said he HEARD they were artificial in nature and that they are made by fusing human and beast soul with dark arts. However, there are too many exemplars of the half-races for that to be the ONLY way they are created: most likely, the first samples were artificial, but then multiplied naturally.
There are several clues pointing towards the theory that she was born that way: the fact she has always been like there is one, the fact Chilchack has seen another catkin before is another.
In addition, the times she was trasformed by the changeling mushrooms give us more information on her situation: first of all, the fact that she change, to begin with, tells us that, whatever she is, it is her foundamental nature, and not an alteration. If she were under an alteration of some sort, either the changeling overwrite the curse, and then at the end she should have returned a human, or the curse was more powerful, and then no matter what the changeling changed her into, the curse should have kept her a cat. Moreover, we were told that changeling transform you into a similar race, meaning she has more in common with the cobolds and the orcs than with the chimera.
In any case, it was clearly stated that this is what she is: even in the case she was actually created from scratch (as was the case for Laius' sister), the human soul was just one of the ingredients involved in her creation, and there is no way to undo the process.
