Urinary biomarkers to assess exposure of cats to environmental tobacco smoke

(Disponible en anglais seulement.)
Cats from households that had owners that smoked had increased urine concentrations of total cotinine, total nicotine, and of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) compared to cats that lived with owners that did not smoke. Biomarkers could initiate the research of the adverse effects of smoking on cats and other animals.

Comment: Pets are often forgotten when discussing the harm caused by secondhand smoke. They also have no way to avoid SHS.
