Dr. Gerhardt, stationed at Frankfurt, worked relentlessly to find out the habits of a lion. He spent hours together in the company of those lions, of course, outside the cage. It is a known fact that the lion is one of the laziest animals. Yet, what Dr. Gerhardt found was astonishing. A lion simply sleeps for 10 to 15 hours out of the 24 hours. Then, it is dozing off for at least 4 to 5 hours. That leaves it with only 7 hours at the most. Then also, it prefers to sit idly, the time ranging from 1 to 4 hours. That surely means that a lion moves around only for an hour or so and at times, this may exceed to 7 hours. You might be thinking that in a zoo each animal is well looked after, hence they afford to be so lazy. But it is not so. The lions at Serengeti are equally lazy. They like to doze off. The lions in a zoo spend hardly 20, at the most 60 minutes for eating. The same applies to the lions in the wild. They need hardly a few minutes to hunt an animal.
