Today, the fruits of Andalus's efforts are evident.
Ratu is pregnant.
Rhinos can't sweat, so wallowing in cool mud is her way of keeping cool.
Essential when you're carrying a baby.
And this is no ordinary pregnancy.
If the birth is successful, Ratu's baby will be the first ever Sumatran rhino born in captivity in Sumatra.
It will be a remarkable triumph for Dedi and his team, as well as for Andalus and Ratu.
We are very happy.
We have been waiting long, long time for this moment.
This is very exciting time for all of us at this sanctuary.
