Everyone is aware that smoking is hazardous to one’s health and that passive smoking is hazardous to the health of one’s family members. It would appear, however, that, not everyone uses this knowledge to pursue it to its logical conclusion – smoking is also detrimental to your pet’s health. Passive smoking can cause respiratory problems and lung, nasal, skin and mouth cancer in animals. A study carried out by Tuft’s University School of Veterinary Medicine in Massachusetts found that continuous exposure to cigarette smoke doubles the chances of cats getting lymphoma and living in a household for more than five years where there is a smoker increased the risk by 400%. Cats are particularly susceptible to illness because when they groom themselves they ingest particles containing nicotine and other dangerous chemicals such as carbon monoxide, formaldehyde, arsenic, benzene from the cigarettes. Research into the effects of passive smoking on dogs carried out by Colorado State University showed higher incidence of nasal cancer, particularly in long-nose breeds of dogs. It also showed an increased risk of lung cancer. Numerous other studies have shown that inhalation of cigarette smoke causes bronchoconstriction and inflammation of the lungs in guinea pigs, laryngeal carcinomas in hamsters, skin tumours on rabbits and mice and pneumonia and lung cancer in birds. So if you don’t want to give up smoking for your sake, give it up for the sake of your pet. Make your home, a smoke-free zone.
