I hail from a place where biological animorphic “Catgirls” exist. They are just as, if not more, intelligent than humans, and have the right to think for themselves. That being said, these hybrids, referred to as “Faunus” are notorious for creating a very violent terrorist organization known as the “White Fang” in which roughly a majority of the Faunus are apart of. For these reasons, to prevent things getting... out of hand, I think it could be potentially beneficial to continue these neurological modifications to a degree. However, members of these species that are allies and known to be trustworthy should be given freedom. A notable example is Bopsheezi and his companions, Mirage and May. They have helped us on numerous occasions and are clearly not terrorists.
