Simultaneous Chemical and Sensory Analysis of Domestic Cat Urine and Feces with Headspace Solid-Phase Microextraction and GC-MS-Olfactometry

The association between humans and cats (Felis catus) is well known. This domestic animal also known for its malodorous urine feces. complexity of the odorous feces impacts human life by triggering sensory organ in a negative way. objective this research was to identify volatile organic chemicals (VOCs) associated odors cat using gas chromatography–mass spectrometry simultaneous analysis fresh aged samples. solid-phase microextraction (SPME) technique used preconcentrate VOCs emitted from or Twenty-one compounds were identified as urine, whereas 64 A contrasting temporal impact observed emission On aging, increased 34 detected stale only 12 Not all malodorous; some had pleasant hedonic smell nose. Although trimethylamine, low-molecular-weight acids, ketones contributors odor extent, phenolic aromatic heterocyclic N generated most intense substantially contributed overall malodor, study. work might be useful formulate remediation approaches reduce impacts.
