The leopard will actually bury her cubs. Having cubs is probably the only sign of affection she will show. Leopards are considered to be close to extinction, and are on the endangered species list. There are over 20 subspecies of leopards. Leopards are 10 times stronger than humans and can carry 3 times their body weight up into trees.
Some leopards are melanistic, which produces a black fur.
Their spots are visible, especially when light is on them. As melanism is a recessive gene, two black parents will produce black cubs, and two spotted can have black cubs. Mixed litters are common. Their heavy coats protect them from harsh Himalayan winters. Like the leopard, they are loners and excellant hunters.
