Lions

Lions are the only cats that live in groups, which are called prides. Prides are family units that may include up to three males, a dozen or so females, and their young. All of a pride's lions are related, and female cubs typically stay with the group as they age. Young males eventually leave and establish their own prides by taking over a group headed by another male. Males defend the pride's territory, which may include some 100 square miles of grasslands, scrub, or open woodlands. These intimidating animals mark the area with urine, roar menacingly to warn intruders, and chase off animals that encroach on their turf.Female lions hunt for the pack. They often work together to kill there prey. Many of these animals are faster than lions, so teamwork pays off.
