We shall refer them as Kemonomimi in this discussion. It has come to my attention how the K will be treated in the future should they be created successfully at the end. Courtesy again to @Martialegg thread and @Chrono Vlad meme. Are K identified as persons or possessions in the distant future? Do they have human rights as persons? Their animal rights as possessions? Both? Are they to be monitored by their guardians as persons or owners as possessions?
Probably start as possessions and then some woke people will not let things be and give them rights and thus a new race of persons might come into existence
If it can understans words, it would have rights. We as human beings are not monsters. We are an intelligent lifeform(uh... Some of us) and as we treat those 'humanoid creatures' (SJWs and whatnot). All life should be respected, even if they are different from us. We are not savages and are civilized men.
I'll adopt any K on my house, anytime. Jokes aside, I think there will be a new law protecting those K. They're considered to be a new ethnicity, I guess. I doubt any slavery or ownership would exist in any form for K.
If a guy knocks-up a catgirl or monster girl through consensual sex, technically that is partial-bestiality, right?
Genetically engineered catgirls would obviously be treated as people if you engineered them from people and they're capable of rational thought and stuff. If they're engineered from cats and basically behave like cats, then there would be some huge ethic debates going on and who knows what would come of it... Probably some weird middle ground.
