Secondhand smoke is dangerous for people and pets, too. According to a study conducted at Tufts College of Veterinary Medicine, kitties face a higher chance of getting certain types of cancer including malignant lymphoma, a cancer that is fatal to three out of four cats within 12 months of developing it. However, simply because of felines natural grooming habits, they also face a great risk of getting mouth cancer. When your pet licks her paw, she is licking up the cancer-causing carcinogens that accumulate on her fur. The study found that more kitties get squamous-cell carcinoma if they live in smoking environments versus those residing in a smoke-free home. The cats are not the only pets in danger, exposure to secondhand smoke can also result in nasal and lung cancer in dogs – pups noses have a greater surface area to be exposed to carcinogens and a shorter nasal passage that allows more carcinogens to reach their lungs. If you're still trying to quit smoking, make sure you don't light up around your pets!
