In the past 45 years, the number of smokers in the United States has decreased to less than 20% of the population and almost 70% of those current smokers want to kick the habit. Could an understanding of how secondhand smoke affects our pets help encourage more people to quit?
The history of smoking tobacco may reach back many hundreds of years, but research in the 20th century has made it clear how harmful this habit is. Furthermore, secondhand smoke has been implicated in the illnesses and even deaths of non-smokers. What?s even more disturbing is that smokers may have unknowingly contributed to severe disease in dogs and cats.
Most people understand that secondhand smoke from cigarettes contains an incredible number of hazardous substances and many of them are carcinogenic. These chemicals are found in high concentrations in carpets and on furniture around the home. This includes pets sharing this environment! These toxins get on their fur and they ingest them during normal grooming.
In the early 1990s, researchers found correlations between nasal cancers in dogs and the presence of smokers in the home. There is also a concern that environmental tobacco smoke may increase the incidence of lung cancer in our canine friends as well.
Cats may actually be at higher risk for serious disease when they live in a smoking environment. As mentioned above, many cigarette smoke toxins settle to low levels in the home and cats will pick up these substances on their fur. Because of their fastidious grooming habits, cats end up ingesting a higher level of chemicals and this leads to a greater chance of several types of cancer.
Lymphoma is a cancer of white blood cells and is one of the most common cancers seen in our pet cats. When smokers are present in the cat?s household, the risk for this killer is increased by two or three times over cats living in non-smoking homes. Sadly, when our feline friends are diagnosed with lymphoma, the prognosis is very poor and many won?t survive another six months.
Another serious cancer with links to secondhand smoke is a cancer of the mouth known as squamous cell carcinoma, or SCC. Studies have linked a higher risk for SCC in cats living in smoking homes. Again, the prognosis is very grave and most pets won?t survive another year.
An unpublished study has also found that the levels of nicotine found in the hair of dogs exposed to second hand smoke is similar to levels found in children living with parents who smoke.
With more than 46 million smokers in North America and about 60% of the population owning dogs or cats, the risk for the animals is substantial. Pets are often good at hiding signs of illness, so many smoking owners fail to realize the damage that their habit is causing to the four legged family member.
Of course, the best course of action is to give up the tobacco habit entirely. It?s not only best for the health of the smoker, it will also greatly reduce risks for pets. Understanding that it?s not easy to quit this addictive habit, people who smoke and have pets should attempt to minimize their pets? exposure by smoking outdoors. If you must smoke when you drive, leave your pets and kids at home!
Pets who are developing illnesses from secondhand smoke may exhibit symptoms ranging from lethargy to coughing to the appearance of masses in the mouth. It?s important to have your pet seen by a veterinarian if any of these signs are noted.
