Villagers heard a deer barking in the distance, but they were not the only ones to hear it. A leopard, stretched full-length on a large tree branch, heard it, too. The leopard raised its head and then got up slowly. Deer were its natural prey, but there weren't many left in this area. So, the leopard began to attack dogs and cattle in the village. After several attacks, the villagers no longer allowed their cattle to wander far, and at night they were securely locked into their barns. Favorite dogs, (a) used to walking / (b) used to walk around the village at night, were now called indoors before sunset.
