How does a kangaroo raise it's chilf?

If one has to ask how to raise a baby kangaroo, then one is clearly not in a position to take on this responsibility. Kangaroos require specialised attention, and that is why only registered wildlife carers are permitted to raise joeys if the mother is unable to do so. Raising a baby kangaroo under any other circumstances is illegal. Please take the joey to a vet who understands Australian native wildlife.
