You live in an apartment building and your next door neighbour always seems intimating and tired

You were doing something on your phone, you suddenly heard some weird noises from the next door, like something breaking

You decide to go knock to check if everything is okay, no answer, you notice the door is open, so you go inside

You hear some quiet cursing and meowing in the living room, you go there and find your intimating and tired looking neighbour, holding a small black kitten
