Love cats but your nose doesn't? A San Diego company is breeding felines that are naturally hypoallergenic. Most cats produce a protein in their saliva that can trigger an allergic reaction in humans; some breeds, like the Siamese, produce less of it than others. But in Allerca's mixed-breed (not genetically engineered) cats, the protein is virtually undetectable. Allerca tests each cat and offers a one-year money-back guarantee. Demand is high: there's already a 15-month wait for the sniffle-proof kitties.
