Only problem I have with nekopara is that some of the cats seem to have the mental age of little children. I think Vanilla was the worst case for me. I also don't like male harem leads, so I'm biased - but the whole ecchi thing later on did put me off.
In this case it seems the "owner" still has to understand what things will change from now on. The cat seems mature enough to know what she wants. Also pet is a vage term, for many people their pets are more like friends, not a toy or something.
