* Rocky outcrops and cliffs: These provide natural barriers and a vantage point for observing the surroundings.
* Hollow trees: Large, hollow trees offer shelter and a sense of security.
* Caves: Caves provide a dark, cool, and dry environment, ideal for raising cubs.
* Dense vegetation: Thick undergrowth provides camouflage and concealment.
* Abandoned burrows: Occasionally, Amur leopards will use abandoned burrows created by other animals.
The specific location of a den can vary depending on factors such as the time of year, the presence of prey, and the availability of suitable shelter.
It's important to note that Amur leopards are solitary animals, and they only share their dens with their cubs.
