Sometimes having a cat for a housemate is great. It can be absolutely blissful when a kitty falls asleep purring in your lap. And they make great pest control. At other times — like when your crepuscular cat gets the zoomies at dawn and knocks something breakable off a shelf as it rushes by — you start to wonder whether it was a good idea to let an animal into your home.
Cats are domesticated animals. That means that they are descended from wild cats. Over thousands of years, those cats have evolved to live in our homes (though they still share many traits with their wild relatives). Now, about a quarter of U.S. households are also home to one or more cats.
Some people, though, are allergic to them. Up to one in five may have a cat allergy. These individuals are allergic to a small protein called Fel d1. It’s produced in a cat’s salivary and sebaceous glands. Cats spread this protein across their fur when they lick themselves. But scientists are working on ways to tame these allergies, from developing better allergy drugs to engineering hypoallergenic cats.
