So the mom was definitely treated as a breeding pool not a proper pet that enables the love towards humans to create a nuko. So basically force mating. Also I'm pretty sure in the backstory of kana that apparently there are two biological parents, and Nuko children(specifically the calico siblings) were a surprise.
How do the cat mother got pregnant when she in captives? She been forced to "love" the old man or what? Nuko are born because of the deep love of the cat towards a human (unknown if it need to be reciprocate, and love only for man etc)
