Well, the game was pretty interesting for sure. I'm not sure what the story is, but I assume that the player received a cat from their girlfriend or their ex-girlfriend and wants the player to take care of it. However, the player not only refused to do their job, but the cat slowly curses him so that it steals the player's humanity every night. The player starts to get shorter and sees cats on pictures instead of humans. Finally, the cat has become a giant bipedal creature and traps the player inside their room. The cat shall now take care of the human, or what has become of him.
Some parts of the game made me feel uneasy like the part where the cat stares at the player with red glowing eyes, and the part where the cat slowly teleports through the hallway and gets closer. I don't know if the game has an ending, as I'm stuck at the part where the giant cat traps the player in their room. But I do like the game's story and how it can be interpreted any way the player wants.
Moral of the story: take care of your cat, or the cat will take care of you.
