“One reason cats are so susceptible to secondhand smoke is because of their grooming habits. Cats constantly lick themselves while grooming, therefore they lick up the cancer-causing carcinogens that accumulate on their fur,” MacAllister said. “This grooming behavior exposes the mucous membrane of their mouth to the cancer-causing carcinogens.” Malignant lymphoma is another type of cancer that cats that live with smokers have a higher risk of getting. This cancer occurs in the lymph nodes and cats are twice as likely to have this type of cancer compared to cats living in a non-smoking home. This form of cancer is fatal to three out of four cats within 12 months of developing the cancer.
