Researchers have identified a new species of wild cat, named Leopardus tilcayo, in Bolivia's Yungas forest. The discovery is significant as it is the first new wild cat species to be described in more than a century. The animal is relatively small, measuring around 45 to 46 centimeters in length and weighing approximately 1.4 kilograms, making it smaller than an average domestic cat.

The identification of Leopardus tilcayo was confirmed through genetic analysis, including DNA from historical museum specimens and samples from live animals. Reports indicate that the cat has light brown fur with irregular rosette-shaped spots. While much about its lifestyle remains unknown, analysis of its droppings suggests a diet of small rodents, and camera trap footage indicates it may be more active at night.

Disagreement on origin of discovery

While most reports agree on the scientific identification and characteristics of the new species, there is a divergence regarding how the discovery was initially prompted. Some reports state that scientists discovered the species through DNA analysis of specimens. Other reports suggest the discovery was initiated when a resident of the Yungas region brought a 'strange house cat' to a local shelter, which led scientists to investigate.

What the coverage left out

None of the left-rated digests mention the detail that only one living individual of this species has currently been confirmed, a fact noted in some right-rated digests.

36 rated outlets

  • Left-rated reports highlighted the significance of the discovery as the first new wild cat species in over 100 years. They noted the scientific name, Leopardus tilcayo, and its classification within the tiger cat group (oncillas). Several left-rated reports mentioned the cat's physical characteristics, including its size (around 46 cm long, 1.4 kg) and spotted fur. The location in Bolivia's Yungas forest was also frequently mentioned. Some reports included details about the cat's potential diet and nocturnal activity, citing Paola Nogales-Ascarrunz as a key researcher. The historical context, referencing the last discovery of a new cat species in 1923, was also a common point.

  • Centre-rated reports focused on the novelty of the discovery, emphasizing that it is the first new wild cat species identified in over a century. They provided the scientific name, Leopardus tilcayo, and its location in Bolivia. Details about the cat's size, described as smaller than a domestic cat, and its leopard-like fur were common. Some reports mentioned that the animal was initially mistaken for a pet or a 'weird house cat', with one source noting its discovery began in 2016 after a wildlife sanctuary received a call about an unusual cat. The scientific confirmation through DNA analysis was also a recurring element.
