Cat Urine Glows Under a Black-Light



July 20, 2024

  • Cat urine can indeed glow under a black-light or ultraviolet (UV) light.
  • This is due to the presence of certain compounds in cat urine that fluoresce or emit a visible glow when exposed to UV light.
  • One of the key components in cat urine that causes this glow is called porphyrin.
  • Porphyrins are organic compounds that are naturally present in the urine of many animals, including cats.
  • When exposed to UV light, porphyrins in cat urine can emit a yellow or greenish fluorescence, making the urine stains visible under a black-light.
  • It’s important to note that not all types of stains or substances will necessarily glow under a black-light, and the intensity of the fluorescence may vary depending on factors such as the concentration of porphyrins and the age of the urine.
  • Nonetheless, the use of a black-light can be helpful in identifying and locating cat urine stains that may not be visible to the naked eye.
