People want to know what lions do in their spare time. Of all the species of cat including domestic cats, lions are the least active. In their spare time they rest. Two prides of lions, one in the Serengeti and the other in Ngorongoro Crater, in Africa, were inactive for an average of about 19 hours per day.
“Inactive” means resting, doing practically nothing. About 2 to 3 hours per day was spent travelling and about one hour was spent hunting and feeding.
Lions in Nairobi National Park have a similar day-to-day schedule of activity and inactivity. They rest the 20 hours, spend three hours moving and hunting and spend about one hour a day feeding.
They travel about 2 to 9 km per day and they travel the longer distances when prey is least abundant. In the arid environment of the Kalahari and Etosha National Park in Namibia where large prey i.e. ungulates are few and far between, lions travel an average of 12 to 13 km per night.
The answer to the question in the title therefore is that lions rest in their spare time. We know domestic cats also rest a lot in their spare time (arguably all their time is spare time!). They snooze although some people think they sleep. The domestic cat might snooze for about 14 hours in one day.
