I'm staying at my friends house for a week, and the place is disgusting. There's cat pee everywhere and she doesn't clean their litter box regularly so it smells really bad. She gets annoyed at me for the littlest things and said it was my fault that her cat peed on my iPad. I'm going to change their litter and clean up a bit, but it's genuinely disgusting and I think I'm going to go home early.
