TLDR; I warned my roommate to close her door to prevent my cat from entering and messing with her stuff. She didn’t and my cat knocked over a plant. Would I be the asshole for leaving it?

Importantish backstory: this roommate and I are finishing our lease only on “amicable” terms. After much bickering of her leaving bags of trash in the apartment hallway and also being unwilling to pay utilities, we barely even say hello to each other. I stay polite and try not to make her feel uncomfortable space though. She currently is also living out of town at her significant other’s parents for the majority of the week. I only see her for a portion of the weekend, if that. 

There is a lot more to us being roommates and how she has wronged me. At the end of the day, I’m grateful I ended up with someone like her and not someone more disrespectful to my space and person. I don’t want to completely sour our relationship, but I would no longer call us friends-just roommates.

Now onto our story: Our apartment is not the best so both of our doors do not shut completely and can be opened with just slightly pushing on hem. My cat has discovered this and makes it a habit to immediately open my roommate’s door whenever he sees it’s closed. This is something my roommate is aware of and complained about to me explicitly. This is on top of her ALSO having a cat who does this to me.

Last week she left chocolate out on her desk, completely in the open. He of course got into it and ate some. After barfing everywhere I rushed him to the vet. He thankfully is fine. Instead of cussing out my roommate for leaving chocolate out, I instead told her that we need to start blocking off the door whenever she leaves. I figured I couldn’t blame her immediately for her actions. This would at least prevent him from hurting himself again and possibly harming any of her stuff, as he is still a kitten. 

Well after staying for the weekend and agreeing to the plan she left. This morning I woke up to my cat chilling in her room and a plant splattered on the carpet. I’m talking dirt everywhere, DEEP in the carpet. At this point I have been very jaded with her actions and behavior. I feel no sympathy after the panic attack it was finding an emergency vet in a town of 5,000 at 8:30 pm. 

Because of this I need honest judgement: WIBTA for leaving that plant, pretending I never saw it, and reminding her that we agreed on keeping the door closed when she brings it up. I feel like I’m not responsible for my cats actions after explicitly warning her and us agreeing.

I know this is inconsequential roommate and girl drama, but I would appreciate some answers on if I am being as much of an asshole as I feel like I am.
