The appeal of animal characteristics and young women found in the playboy bunny suit is what allegedly spawned the Nekomimi character type. It is (apparently) seen in other ways beside sexual, not saying there isn't sexuality involved, but apparently there is other associations.
I feel like I don't have enough inside knowledge of the culture to feel comfortable definitively saying that the creators meant solely sexual design.
