The Smithsonian National Zoo's dedicated keepers work to engage lions, cheetahs, and bobcats through enrichment activities that mirror their natural behaviors. Katy Juliano, who oversees the lions and bobcats, alongside Adri Kopp and Amber Dedrick, who focus on cheetahs at the Smithsonian Conservation Biology Institute (SCBI), employ various methods to encourage movement and socialization among the animals.

Enrichment is vital for the well-being of these great cats and involves a range of activities, from chasing balls to exploring new scents. It goes beyond simple toys and is as essential as proper nutrition and medical care in promoting their natural instincts.
At the National Zoo, three male and three female lions reside. Sisters Naba and Shera, along with Shera's daughter, Amahle, live in one pride, while the male lions, Shaka and Jumbe, form a brotherly duo. Luke, their father, is housed separately to prevent breeding. Lions are social animals, and their interactions mirror behaviors found in the wild, such as the females playfully stalking one another.
Adri Kopp highlights the unique qualities of cheetahs, as SCBI operates as a breeding facility for 29 cheetahs, collaborating with various organizations to maintain a genetically diverse population under human care. The cheetahs enjoy several outdoor enclosures, promoting exploration through new environments, and physical structures like hammocks enhance their habitat.
The cats benefit from interactive feeding methods, with carcass feedings scheduled for lions and bobcats every third Sunday. This practice not only meets their nutritional needs but also prompts natural behaviors associated with hunting.
Scent plays an integral role in the lives of lions and bobcats, with keepers using over 30 unique spices for enrichment. Lions are particularly drawn to earthy scents, while bobcats enjoy scents like men's cologne. In contrast, cheetahs, with their less developed sense of smell, prefer moving enrichment items rather than scents.
Various enrichment techniques include using jolly balls that roll and bounce, providing physical activity. For example, cheetah cubs engage with floating toys in water, challenging their problem-solving skills.
In the field of wildlife care, aspiring keepers are encouraged to gain experience through animal shelters, veterinary clinics, or wildlife rehabilitation centers. The zoo also welcomes donations to support the enrichment programs that enhance the lives of their animals.
