Secondhand Smoke Leads to Higher Risk of Cancer in Cats

A recent study from Tufts University Cummings School of Veterinary Medicine shows that cats have an increased risk of developing cancer if they live in households with smokers. It can take hours for the smoke of one cigarette to clear from the air. It is believed that smoke & nicotine residue in the air gets on the cat’s fur so they are exposed to these toxins by breathing and by grooming themselves. Cats have twice the risk of developing lymphoma, one of the most common cancers in cats, if they live in a home with one smoker and up to four times the risk if they live with two or more smokers. We do see cancer in cats living in smoke-free households, but we all want to lower the risk.
