South Korean scientists tinkering with fluorescence protein genes say they have bred white Turkish Angora cats to glow red under ultraviolet light.

The pair of cats cloned from a mother’s altered skin cell are nearly a year old. The researchers told the AFP that their work could help unravel mysteries of some 250 genetic diseases suffered by both humans and cats. The findings also could be used to clone endangered tigers, leopards, and other animals, the report said.

However, it’s unlikely that such psychedelic-looking cats would come to pet stores anytime soon. Debates about the ethics and safety of concocting cloned and transgenic animals continue to rage.
