Listen, when Mr. Furr2D2 got the hairball that never went away, I brought him to the vet. The vet said, “Your cat has asthma.” I said, “Could that be from my smoking?” The vet explained there’s a variety of research that suggests that secondhand smoke is a well-known asthma trigger in humans. While not as much research has been done on pets, a recent Tufts University study did find an association between secondhand smoke and cancer in our four-legged friends. WHAT? If Mr. Furr2D2 got cancer, I’d be the saddest robot ever.
