Cats are exposed to parabens, common industrial preservatives, with all four tested parabens detected in their hair. Higher levels of propylparaben were found in indoor cats, suggesting potential health risks.

Area of Science:

Environmental Science
Toxicology
Veterinary Medicine

Background:

Parabens are widely used industrial preservatives found in various products.
Environmental contamination by parabens is a growing concern, impacting ecosystems and living organisms.
Limited data exists regarding feline exposure to parabens.

Purpose of the Study:

To quantify the levels of common industrial parabens in cat hair samples.
To investigate potential correlations between paraben exposure and factors like indoor/outdoor access, sex, age, and body condition in cats.

Main Methods:

Analysis of four parabens (methylparaben, ethylparaben, propylparaben, butylparaben) in 70 cat hair samples.
Utilized liquid chromatography-triple quadrupole mass spectrometry for precise quantification.

Keywords:

aggregate exposure biomonitoring cats endocrine disruptors hyperlocal exposure

Collected data on signalment, body condition score, and outdoor access for each cat.

Main Results:

All four parabens were detected in every cat hair sample analyzed.
Methylparaben, ethylparaben, propylparaben, and butylparaben were quantified with varying concentration ranges and medians.
Significantly higher propylparaben levels were observed in strictly indoor cats compared to those with outdoor access.
No significant differences in paraben levels were found based on the cats' sex, age, or body condition.

Conclusions:

Cats exhibit considerable exposure to common industrial parabens.
The presence of parabens in cats suggests potential negative impacts on feline health.
Further research is warranted to understand the full health implications of paraben exposure in cats.
