A dog returning from a walk in the rain, a litter tray gradually giving off an ammonia-like smell, or a fabric permeated with lingering odours: these situations, familiar to many households, reflect a reality far more complex than mere olfactory discomfort.

Today, odour management is a key factor in the choice of pet products, with nearly 70% of owners considering it a major priority [1]. This growing demand reflects changing expectations, where olfactory well-being has become inseparable from overall well-being, both for the animal and its environment.

Behind this everyday issue lies a rich field of scientific study, at the interface between microbiology, analytical chemistry and sensory sciences.
