if you groom your cat fastidiously you’ll be fine. the allergen is not in the hair, it’s in the saliva.

i am allergic but have a long haired cat. it’s fine as long as i brush him out regularly. when he bites me i break out in hives though.

it’s also not true. hypoallergenic dogs/cats are just marketing nonsense designed to appeal to rich weirdos who want to spend five figures on dog because they think nothing has any value if they pay less than that.

for bragging rights

there are also purebred cats that cost 4-5 figures.
