Veterinary researchers have discovered that cats “glow” in the dark, according to a new study published in the journal Royal Society Open Science.

Scientists in Australia analyzed a museum’s collection of mammals to see how many glow in the dark with a UV light turned on. They also tested the glow to see if it was actually fluorescence and not a different phenomenon.

…

They found that 125 species had the fluorescent properties that allow them to glow in the dark under a UV light, including the domestic species of cat (Felis catus).

“We report fluorescence for 125 mammal species, from half of all mammalian families and representing almost all clades in the mammalian phylogeny,” the scientists wrote.

Other mammals that were found to illuminate under UV lights include bats, platypus, koalas, polar bears, zebras, dolphins and humans.

“The only major mammalian clade missing from our dataset is the lemurs… [and] we predict this clade will also contain fluorescent species,” the authors added.

While there are various forms of fluorescence, all include the absorption of light and a low-level emission, which often results in a glow.

“Fluorescence was most common and most intense among nocturnal species and those with terrestrial, arboreal and fossorial habits, with more of their body being more fluorescent,” the authors wrote.
