Researchers have identified an entirely new species of wild cat, marking the first such discovery in a century. The animal, scientifically named leopardus tilcayo and affectionately dubbed the “tilcayo tiger cat,” was confirmed to exist after genetic testing revealed it as distinct from all previously known felines. The finding, published this week in the journal Current Biology and reported by NBC News, stems from a chance encounter at a wildlife rehabilitation center near La Paz, Bolivia, where locals had initially mistaken the small spotted cat for an ordinary domestic kitten.
The tilcayo tiger cat is notably smaller than the average house cat, featuring rounded ears, a slender build, and a coat marked with spots. Its discovery in the Bolivian Yungas—a lush, mountainous region of cloud forest—adds another chapter to our understanding of South American felids, even as scientists acknowledge that the exact size of its wild population remains unknown.
A Chance Encounter That Sparked a Discovery
The journey toward this scientific breakthrough began with an ordinary man living in a forest community near La Paz. According to details recorded by the sanctuary where the cat was taken, he had found the small animal and cared for it as though it were a domestic kitten, feeding it noodles, rice, and eggs. Only later did he realize the creature was wild and beyond his ability to care for.
“The cat had been brought in by a man living in a community in the forest near La Paz who had mistaken the cat for a domestic kitten,” NBC reported, citing the sanctuary’s records. “He had fed the animal noodles, rice and eggs, only to realize it was wild and that he could not take care of it. So he brought it to the sanctuary.”
Paola Nogales-Ascarrunz, co-author of the study in Current Biology, came across the cat while volunteering at the wildlife rehabilitation center. Something about its appearance struck her as unusual enough to warrant deeper investigation.
Genetics Reveal a Distinct Species
Initially believed to belong to an already known species of wild cat, the animal’s true identity was only confirmed through genetic testing. The results ultimately revealed that this small feline represented its own distinct species, separate from every other documented member of the genus leopardus.
Rather than assigning a new scientific name chosen by researchers, Nogales-Ascarrunz and her colleagues honored the animal’s established place in local culture. The community had long referred to the cat as “tilcayo,” a term passed down through generations.
“This cat, they call it tilcayo. And when you ask, ‘Does it have some meaning in Quechua or Almyra and other Indigenous languages?’ they say, ‘No, my grandpa told me that’s the tilcayo.’ This is a traditional knowledge that they have in the community. We want to preserve that knowledge and we didn’t want to give it another name.”

A Conservation Concern for a Little Cat
While the tilcayo tiger cat may be brand new to Western science, its existence is far from surprising to Bolivian communities who have been aware of it for years. The more pressing question now facing researchers is whether the species can survive.
Nogales-Ascarrunz’s greatest worry centers on preserving the little cat’s future. The five tiger cat species native to Central and South America already inhabit regions where conservation efforts are threatened by development and agricultural expansion. As forests give way to farmland, these small wild felines face mounting pressure.
The discovery underscores a broader challenge facing wildlife researchers across Latin America: documenting biodiversity before it vanishes. Each newly identified species offers both a scientific milestone and an urgent reminder of the fragility of the ecosystems they inhabit.
Looking Ahead
With the tilcayo tiger cat now formally recognized, attention turns toward understanding its population size, habitat range, and conservation needs. Researchers hope that formal recognition will help protect the species and its cloud forest home from further encroachment.
The five American tiger cat species—along with this newly documented addition—will require ongoing study and protection if they are to endure. For now, scientists celebrate a remarkable discovery made possible by an observant volunteer, a caring local resident, and the enduring traditional knowledge of Bolivian communities who knew the tilcayo long before it ever entered the scientific record.
