Cats are more predisposed to getting malignant lymphoma and dogs will be subject to nasal or lung cancer. Not only do pets share our homes and breathe the same air as we do, but their grooming behavior and somewhat more homebody-like lifestyles may increase the intensity and duration of their exposure to smoke compared to that of the humans in the household. Not only do dogs and cats inhale our cigarette smoke, but they also receive a double dose of nicotine when they clean their fur, ingesting nicotine that is on and in the hair. Additionally, pets live lower to the ground than we do and are exposed to smoke residue that has settled out of the environment and adhered to carpets, upholstery and bedding as they sleep in various spots in the house over the course of a day.
