This roommate situation has officially gone off the rails… and possibly off the lease. They both agreed to a no-pets policy for a reason, and cat allergies aren't just a mild inconvenience. Sneezing, itching, wheezing, living like that daily is no small hissteria.

So when Lily waltzed in with a surprise emotional support cat and declared the rules no longer apply? That's where things got whisker-twisty. Emotional support animals can be a legitimate need, but that doesn't cancel out someone else's health needs or give a free pass to break the lease without a conversation.

It's one thing to need support. It's another to completely ignore boundaries, go full stealth-mode with a furball, and then cry foul when asked to find a compromise. That kind of cattitude is bound to spark tension in any shared living space.

It's about coexisting. And right now, one person's needs (and sinuses) are being trampled while a sneaky new roommate prowls the halls. Someone's got to step up and set things straight before this apartment turns into a full-on cat-astrophe.

    So I (26F) live in a 2BR apartment with my roommate Lily (27F). When we moved in 6 months ago, we both agreed on a strict no-pets policy, which is also in our lease. I'm allergic to cats, which Lily knew about, and it's one of the reasons we picked this place.

    Last week, Lily brought home a cat, saying it's her new "emotional support animal" that she got from a friend. She just showed up with it out of nowhere and said, "It's not a pet, it's a medical necessity, so the no-pets rule doesn't count." She didn't even talk to me about it first.

    The cat has already been making my allergies flare up. I told Lily I get that she might need support, but the lease says no pets, and my allergies are really bad. I suggested she find the cat a new home or move out if she needs the cat that badly. She got super

    AITA for sticking to the no-pets rule even though she says it's for her mental health?

    OkActuator1742 I would feel the same way. You didn't sign up to live with a cat, especially when it makes you sick. She should've at least talked it out with you first. Emotional support doesn't mean ignoring someone else's health needs.

    cachalker Ok, she can't just move her pet into a no-pets leased apartment simply by calling it an ESA. She has to provide documentation from a mental health provider that the ESA is necessary. No documentation. Landlord is not required to accommodate her. Just report her to the leasing office. And ask the leasing office about transferring to a 1BR.

  • We all feel emotionally supported by our cats. How could we not? But if you’re calling it an ESA to bend the rules, you’ve gotta have the proper paperwork to back it up.

    Sudden_Waltz_3160 Depending on where you live, "emotional support animals" can have legal protections...assuming she has a note from a medical or mental health professional, which is generally easy to get. I don't know how that works when stacked up

    Ok_Childhood_9774 NTA, and Lily needs to find a new home for her cat (and maybe herself). No pets. means no pets. If she can't honor that, then she needs to go.

    Dragon_Queen_666 NTA. Go to the landlord. She's risking your health over this. She's got to go. Tell the landlord that you had nothing to do with her decision to bring an animal into the house.

  • Might be time to loop in the landlord and let them know what’s going on. If it’s in the lease, they’ll probably want to know there’s a surprise cat involved.

    nottobetruffledwith- NTA. She can't just claim a cat is an emotional support animal..I'm pretty sure there's actual paper work that has to go into that for it to be considered lol. Someone please feel free to correct me if I'm wrong.

    Pristine-Local-8176 NTA. Lease says no pets. You have allergies. She's weaponizing her "mental health" to force you into letting the cat stay. If she really needs the cat that badly, she can move and go through whatever process there is for an emotional

    against a roommate with pet allergies, but I would look into the local laws before acting, as you may open yourself up to litigation if you are not careful. And no, that isn't fair, but "fair" and "legal" don't always line up.

    support animal and get her own place. I say all of this as a cat lover - I have two. I'd never move in with someone and expect them to just suffer and deal with it.

    LvBorzoi OP...NTAH...by a mile Here is what I would do. I would go to your doctor and get a note certifying you extreme allergy to cats stating that you cannot live with one.

    Tell Lily you are meeting with the landlord and have a note from your doctor certifying you extreme allergy and asking that you be released from the lease to find an apartment that meets your medical needs.

  • Allergies aren’t just a minor inconvenience. They can seriously impact your health. And if she agreed to no pets from the start, it’s not fair to suddenly change the deal.
