My now wife didn't really like cats when I met her and was allergic to the point of the hair giving her little welts.
Fast forward a couple few years and she loves my cat and just ends up taking allergy pills every day and dealing with the itching.
Fast forward a few more years when that cat dies and she says she doesn't think we can ever replace him.
Fast forward one month and she comes home with a flyer for a rescue cat she wants to adopt.
And we did and she couldn't be happier.
