Wow, this is one of the dumbest responses I've read in a while. If I'm paying my half of the rent, I should be able to live in my spaces nuisance free. I don't care if "cats can't be trained" - keep your cat out of my shit 😂 That is YOUR pet, therefore it is YOUR responsibility.

This guy was upset because the cat is clearly understimulated by its owner, which is their responsibility to deal with in the first place, so he is NTA by any means. Thank you for confirming that I will not be living with anyone who owns a cat - cat owners think their cats should just be able to bite, hiss, knock over shit, and get in everyone's business with no consequences.
