Chinchilla rat
（重定向自Abrocomidae）
Chinchilla rats or chinchillones are members of the family Abrocomidae. This family has few members compared to most rodent families, with only 9 known living species. They resemble chinchillas in appearance, with a similar soft fur and silvery-grey color, but have a body structure more like a short-tailed rat. They are social, tunnel-dwelling animals, and live in the Andes Mountains of South America. They are probably herbivorous, although this is not clear.
