I live in an apartment with 4 other people. This summer, the 4 of them stayed at the apartment while I went to stay at my parents house. I'm planning on moving out this semester and am in the process of tenant replacement for my room. However, I went over to the apartment today to retrieve something and found that my room had been turned into a cat sanctuary. All my belongings were jammed into my closet, there's cat litter all over the floor, and cats sleeping on my bed that's riddled with cat food and cat piss. Did I mention there's a no-pet policy at my apartment? If I report this to the landlord, there's a chance that my roommates will be evicted. Since it's a joint lease, there's a chance that I might be thrown into this as well, even though I had nothing to do with it. The best case scenario of me reporting them is that they lose their cats, the worst case scenario is that we all get evicted. My emotional side is telling me to report them because I'm pissed as hell, but my rational side is telling me to let it go to avoid any evictions. What should I do?
