Understanding Cat Urine and Its Removal
Why Cat Urine Smells So Bad
Cat urine has a distinct and unpleasant smell, which worsens over time due to bacterial decomposition.

In older cats and unaltered males, the urine is particularly strong due to inefficient kidney function and the presence of hormones.
