Hattie is a spotted Hyena, the most common predator on the wide-open grasslands of East Africa. With her oddly sloping back, shabby spotted coat, tatty tail and toothy grin, when she is fully grown she will stand about 85cm at the shoulder and weigh up to 80kg. Hattie and Herbie were born in an underground den. Within minutes of their first breath, Hattie and Herbie were fighting to see which one would be the top dog. A quarter of cubs die from this sibling rivalry. Spotted Hyenas are skilled hunters and loving parents. There are about fifty hyenas in Hattie's clan, but some clans contain up to one hundred individuals. Each clan's territory covers up to 1000 km. Hyena's are social animals and from an early age cubs spend time out of the birthing den getting to know other member of the clans.
