Other than allergy medication, I don't think there's very much you can do. :(
allergy medicines (don't work for some), bathe him on a regular basis, brush him twice daily away from DH. Have DH wash his hands frequently, etc etc etc... I've got two indoor kitties and I'm allergic.
he is a cute kitty , ask your vet , someone told me they make a shampoo that can help reduce people allergies to thier pets, just regular bathing can help its usualy the animals dander that causes allergies
I don't know the name of it, but there is a solution that you can buy at Petsmart/Petco that you apply to their fur that makes humans less allergic to them. My DH had allergies to my kitty when we first started living together and this helped. He built up a tolerance over time and now he's okay as long as we keep the kitties out of our bed.
are you ok with another woman calling your husband "hun" or "babe"
