What Causes Cat Urine Smell in Indoor Environments?

Cat urine smell in indoor environments can be attributed to several factors, primarily related to the composition of the urine and the conditions in which it is found.

• Urea: Urea is a major component of cat urine and can break down into ammonia when exposed to air. This breakdown process creates a pungent smell that can be particularly strong if the urine is not cleaned promptly.
