Why are some people allergic to cats?
It's not the cat's fur that causes allergies. It's a protein (FEL D1) in the cat's saliva. When a cat grooms itself, it deposits this protein on its fur (and the protein then may be transferred to upholstery and carpets). Some cats have less (or more) of this protein. Though there is no way to predict which cat in a litter, if any, will be less hypoallergenic, though females seem to be the lesser hypoallergenic. Bathing a cat reduces the amount of protein in the cat's fur, so the human's physical reaction is lessened. I have also been told that putting a few drops of vinegar in the cat's water bowl helps to minimize the effects of the protein.
