Nirni cursed the Khajiits deserts and forests because she did not like Azurah

"And Fadomai said, "The Khajiit must be the best survivors, for Nirni will be jealous, and she will make the sands harsh and the forests unforgiving, and the Khajiit will always be hungry and at war with Nirni.""

- Words of Clan Mother Ahnissi

Anyway, onto my interpretation of why the Khajiit may be special to keeping Nirn from falling back into Oblivion.

"Your eternal motions will protect us from Ahnurr's anger." And the moons left to take their place in the heavens. And Ahnurr growled and shook the Great Darkness, but he could not cross the Lattice."

- Words of Clan Mother Ahnissi

The Lunar Lattice keeps Ahnurr(Anu) from reaching and potentially destroying existence. Perhaps the Moons are a tower.

"And Fadomai said, "The Khajiit must be the best climbers, for if Masser and Secunda fail, they must climb Khenarthi's breath to set the moons back in their courses.""

- Words of Clan Mother Ahnissi

Here we see that the Khajiit have a special charge to maintain the lunar lattice.

"And Azurah bound the new Khajiit to the Lunar Lattice, as is proper for Nirni's secret defenders."

- Words of Clan Mother Ahnissi

The Khajiit, even though being reviled by other races, are true defenders of Nirn.
