the rodent so soft it never bathes in water, only in dust.

means A small, plush-furred South American rodent prized for having the densest fur of any land mammal, now kept both as a pet and, historically, hunted for that fur.

from The name comes to us through Spanish, from a word in the Quechua-speaking Andes where the animals live. The popular gloss is that it means 'little Chincha,' tying the creature to the Chincha people of the region — and that link is plausible, though the exact root is debated. What's certain is that Spanish colonizers carried both the animal and its name back to Europe, the diminutive '-illa' ending settling neatly onto a creature small enough to cup in two hands.
