Abstract: Bisphenol A (BPA) is a synthetic organic compound commonly used as a plasticiser in the industry. It pollutes the environment, harms human and animal organisms, and exhibits endocrine-disrupting properties. Companion animals, living in proximity to humans, are highly exposed to BPA. However, knowledge of cat exposure to this compound is extremely scarce. In the present study, BPA levels were analysed for the first time in cat hair using liquid chromatography-triple quadrupole mass spectrometry. BPA concentrations ranged from below the limit of detection to 955.4 pg/mg, with a mean (±standard deviation) of 67.98 ± 145.2 pg/mg and a median of 27.3 pg/mg. Higher levels of BPA have been found in the strictly indoor cats (mean 79.45 ± 162.2 pg/mg, median 35.3 pg/mg) than in cats with outdoor access (mean 25.93 ± 8.07 pg/mg, median 24.4 pg/mg). Some differences in BPA levels have also been noted depending on age and body condition scores. The results show that cats are exposed to BPA to a considerable extent, and the levels of this compound in hair may depend on many factors. It can be assumed that BPA may negatively affect cat health, but due to limited knowledge of BPA metabolism in cats and its harmful effects in this species, many aspects of these issues require further comprehensive studies.
