A study by the Cummings School of Veterinary Medicine at Turfs University found that second hand smoke can also pose health issues to our furry friends.  

Results showed that there is relatively strong link between second hand smoke and cancer in cats; the risk is higher when the animal has been exposed five years or longer. Another study by Tufts College of Veterinary Medicine found that the reason why felines are highly susceptible to second hand smoke could be because of their grooming behaviour, where they expose the mucous membranes of their mouth to cancer-causing chemicals.

Canines with longer muzzles ran a higher risk of nasal tumours due to a greater surface area  in which the toxins can accumulate. While those possessing shorter snouts had definite links to lung cancer as their muzzles aren’t effective in accumulation , resulting in carcinogens reaching the lungs.

As for birds, lung cancer and pneumonia seem to be the main result of second hand smoke.

In addition to listing tobacco smoke as a toxin dangerous to our domestic pets, the medical director of ASPCA Animal Poison Control Center, Dr Sharon Gwaltney-Brant says that our furkid’s nervous systems are also affected, “This is because environmental tobacco smoke has been shown to contain numerous cancer-causing compounds, making it hazardous for animals as well as humans.”
