My Boyfriend Only Allergic to My Cat, No More

My boyfriend is allergic to cat hair. When he was seven, his stepmother locked him in with a feral cat on purpose, and he ended up covered in scratches and a rash bad enough to need emergency care. Ever since, Cameron has hated anything that has to do with cats. But I have an orange cat, Biscuit, that I've raised for six years. He's family to me. One time I just happened to get a little of Biscuit's fur on me by accident. Cameron wouldn't touch me for a whole week, and told me to keep my distance from Biscuit.
