@Goura I'm personally uncertain if a genetic analysis was conducted, to re-evaluate their identification from M. meminna to M. kathygre, but within Joel Sartore's Night Safari catalogue and their Excel diet chart, they're labelled as 'M. kathygre'.
There are three females in the collection.
Were they exhibited in the Singapore Zoo when you took this shot?
Last time I saw them was at Leopard Trail in NS.
