But life in the desert also suits Caiti and Kelp well.
They are excellent burrow builders and spend most
of their time inside where it is cool and safe. Desert
tortoises can go without drinking water for over a
year but besides drinking it they can also get water
from the plants and grasses they eat.

The Burrow (Book 1 Chapter 1)

Caiti and Kelp are tortoises that live in
the Mojave Desert. Life in the desert can be hard.
During the worst of times, they experience extreme
heat and get very little water. Sometimes, even when
it does rain, the extreme heat causes the rain to
evaporate before it hits the ground.
