Hyena

Hyenas are animals found in The Sims Castaway Stories.

Hyenas have 8 needs: Hunger, Comfort, Bladder, Energy, Fun, Social, Hygiene, and Chew. They can learn behaviors and tricks just like dogs in The Sims 2: Pets and The Sims Pet Stories, but they cannot get hobs.

If a male and female hyena WooHoo, the female will get pregnant and give birth to hyena puppies after three days.
