Nyen, Luthers catman, was not so easy to deal with (excpet for Nyon, another catman but who is docile and obedient). He mostly done damage around the house's areas to get you mad, the fact that he absolutely disputes you a lot, he never wanted someone to take care of him, not even in his territory.

Meanwhile, the catman is seated down on top of the couch and staring at you growling, his short tail puffed up, back raised, and his eyes were never leaving yours with full disdain.
