It’s interesting to note that before Lifestyle Pets found the proper pets to breed, they actually turned to gene modification to produce their first batch of hypoallergenic pets. The scientists isolated the protein responsible for producing the allergens in cats and destroyed it with a method called “gene silencing.” As the name suggests, it can be a very torturous experience for the animal—and perhaps an unjust one, considering the pet owner could just vacuum more often and maybe take some antihistamines now and again.
