There is no such thing as a completely hypoallergenic cat or dog. Some cats and dogs may produce fewer allergens than others and may be less likely to cause an allergic reaction in people who are sensitive to allergens, but no cat or dog can be considered completely hypoallergenic. Some people may be more sensitive to certain breeds than others, and some breeds may produce fewer allergens or have a coat that is less likely to shed allergens, but there is no way to predict how any individual cat or dog will affect a person with allergies. If you have allergies and are considering getting a cat or dog, it is important to spend time with the animal and see how you react before making a commitment to care for it.
