- [Narrator] Here in the highlands, the wolf's staple diet is rodents.

They are everywhere.

Grass rats make a tasty meal, but they live in a colony and are hyper-vigilant.

An easier meal can be found in the bigger, juicier giant mole rat.

Living alone, these unusual-looking rodents rarely stray far from the safety of their burrows.

The wolves employ a range of tactics to get to the mole rats.

Some try digging them out.

Others use their long slender muzzles to reach into the burrow, which isn't always successful.

Patience is required.

Eventually, the mole rat can't resist a leaf just out of reach.

Lunch at last.
