Biologists discovered the first confirmed ocelot den at the Laguna Atascosa National Wildlife Refuge.
This is the first time a den has been found in 20 years.
Inside was a three week old ocelot.
The ocelot is an endangered wildcat that lives in parts of Arizona and South Texas.
This year biologists have observed at least three kittens at the Yturria Conservation Easment of Willacy County.
