The sequence leading up to the evening is great, and feels like a real world..
Since I was already familiar with the story of the monkey's paw, I didn't much care for a an exact retelling, which didn't seem to fit the world you had built.. Maybe that could have worked if it integrated more into the world - perhaps an alien artifact and with a different sequence of events than the monkey's paw story. But is this thematically important to the father's life? I'd be more interested in why the cats are doing bizarre things, is there something agitating them? Is there some mystery involving the company the son works at?
Great voice acting and art, would definitely play another game that takes place in the same world.
Oh and it just occurred to me, the monkey's paw is definitely a convenient way for the company to avoid blame for dangerous work conditions. Yeah they are totally liable.
