As stated above, Jonathan was a co-host of Big Cat Diary. Along with other naturalists, Jonathan tracked down and documented the lives of several big cats. His co-host Simon King documented the lives of the Marsh Pride lions and the life of a solo female lioness, Bibi, who had cubs but was shunned from the Marsh Pride. During all this Scott documented the cheetah Kike with her three nine-month-old cubs while Saba Douglas-Hamilton documented the lives of leopard Bella and her two cubs (Chui and unnamed female).
