Cats, dogs and other pets are also affected by passive smoking, which is dangerous for their health, according to a study by the University of Glasgow.
Damaged cells, weight gain after castration and increased possibility of contracting certain cancers. This is what awaits your little companions if you expose them to cigarette smoke. A study from the University of Glasgow establishes a link between a smoky environment and an increased risk of diseases in pets. " We have already shown that dogs absorb a significant amount of smoke when they live in a house ”, said Clare Knottenbelt, professor of medicine and oncology at the Scottish University Veterinary Institute in a statement. " Our study on cats shows that they are even more affected, perhaps because of their meticulous grooming which would increase the amount of smoke absorbed by their body.« 
The study also shows that the levels of nicotine in the body hair decrease significantly if the consumption in the house drops below 10 cigarettes per day. The Glasgow researchers also found in the testes of castrated males a damaged cell marker gene more present in dogs living in a smoking household. This gene is altered in some canine cancers, and it is less so when the owner smokes outside the home, reducing the exposure of their favorite animal.
« The risk for the smoker doubles as the risk of passive smoking for others, and dog and cat owners often forget the risk they pose to their pets“, Underlines the professor, who pleads for the cessation of smoking,“ the best solution for the health and well-being of your companion"
