Eucalyptus leaves can make most animals sick because they have a kind of poison. Koalas still eat these leaves and do not get sick because:

  1. Koalas have special tummies that can handle the poison.
  2. They pick leaves that are easier to eat and have less poison.
  3. They eat slowly and not too much at once.

So even though the leaves have poison, koalas are built to eat them and stay okay.
