almost the entire globe, rodents have learned to thrive in deserts,
grasslands, and especially around human settlements, where some
species (like mice and rats) have become common pests. Humans keep
some rodents as pets, but even wild ones (such as squirrels and
chipmunks) have learned to live in harmony with us in the city and
suburbs. Although usually thought of as small -- with the more common
species being small enough to hold in your hands -- there are others,
like the Capybara, which can grow to the size of small dog.
