I’m not sure I follow you. Yes, this would be a problem if people would, indeed, create mostly nonsentient catgirls. But I’m pretty sure that most people would prefer to have sentient companions. Even if they didn’t, they’d want companions that seemed like they were sentient, and the easiest way to create truly sentient-seeming companions is probably to create companions that are sentient (remember the Zombie Arguments). So the exact problem you’re describing won’t be an issue.
Also, most people will want human-like companions, not things with an obviously alien cognitive architecture. So it seems to me that a far more likely scenario is that a major fraction of the populace will go on to create themselves sentient companions, who they then live with happily ever after (or whatever). There’s no divide into separate societies, since those new companions will be mainly human-like as well, and thus will have lives apart from simply being mates and will integrate into society just as much as everybody else. (This ignores the people who don’t actually want companions but devoted slaves. They might split off, but they’re a minority.)

No problem as I can see it.
