All cats produce dander, even if they don't have hair, so there are no truly "hypoallergenic" breeds. Some breeds have gained a reputation as hypoallergenic, probably because they tend to be bathed and groomed more frequently than other breeds, leaving less dander to be cast into the air.
Still, cats that shed profusely may cause more problems for allergic owners, simply because their loose hair -- contaminated with dander and dried saliva -- is more plentiful, and ends up on furniture, in rugs, and just about everywhere. For this reason, there may be some benefit to these breeds that shed little or no hair:
- Devon Rex
- Cornish Rex
It's also worth noting that male cats generally produce more allergens than female cats do.
