The Effect Secondhand Smoke has on Your Pets

My Pets? Can Secondhand Smoke Harm Them?

We know that secondhand smoke is harmful to others, but is it harmful to our pets?

Yes, it is. But what diseases are linked to it? Cats exposed to secondhand smoke are three times as likely to develop feline lymphoma and dogs are also very susceptible to smoking related respiratory problems and nasal and sinus cancers.

Think about when you smell smoke in someone’s home, and then think about the fact that a pet rests their face right on the fabrics that absorb and keep in smoke, such as a couch or a chair in the living-room. It effects their living environment in a huge way.

Other types of pets are also affected by secondhand smoke too.
Studies show that many types of pets have a higher risk of health problems such as cancer and heart disease.


  • Rabbits get more heart diseases.
  • Hamsters and other rodents get more cancers.
  • Birds have extremely sensitive lungs. Being around secondhand smoke can cause serious lung problems, including lung cancer.
  • Long-nosed dogs are twice as likely to develop nasal and sinus cancers. Short-nosed dogs tend to get lung cancer.
  • When a cat cleans itself, it ingests a large dose of chemicals in the smoke.
