@FirstProgenitor it depends wildly on how bad is bad and what other things you're allergic to (and how hypoallergenic the cat is - there aren't really defined breeds like there are with dogs, it's a bit of a tossup)
allergies often operate at a threshhold model - basically if enough things stack up, you'll be symptomatic. so it could be that you're ok with cats as long as you're taking an anti-allergy med *and* you're also wrangling your other allergies (dust mites, mold, etc). >
@FirstProgenitor the expensive solution that's sadly only really available if you have good insurance is allergy shots. they take awhile of doing a once-a-week injection, but it means you get your body used to not being allergic to bullshit overall. and since it's all your allergies at once, for the rest of your life, it's a fantastic long-term solution to get things down where even with a cat, your body's total 'things we're being allergic to' doesn't meet the threshold (if that makes sense).
@FirstProgenitor yeah, def keep it in mind for when you have insurance! if you've ever had asthma, too, insurances will leap at the chance to get you allergy shots. (because from their point of view, asthma complications can get *very expensive very quickly* lol.)
for right now though you can always look up strategies to cut down on other common allergens (like mold, pollen, dust mites) and see if maybe that gives you some wiggle room to possibly put a cat in there ^0^
