Lions are social animals that live in prides, these are family units that can include up to three males, a dozen or so females and their young. The pride's lionesses are related and female cubs will usually stay in their pride. Male cubs will usually join another pride, taking over a group headed by an older male.
Amur tigers (from a region of Siberia) are the largest of the big cat species and are renowned for their power and strength. There are only an estimated 400 to 500 Amur tigers living in the wild, in the birch forests of Eastern Russia.
