Apartment is no good for a cat but suddenly fine for you? It isn’t like it is in human nature to live in a shoebox either. Human nature is to live in the sahel, sleep under the stars, forage, and track game. The office and the apartment is genuinely a prison for the human in their evolved element.
Look at how much hair is on your skin, you aren’t meant for that. You are meant to persistent hunt game and forage in fairer weather. You are optimized for that. Everything else is compromised, swimming uphill only bailed out by happenstance technological affordance.
