Answer:
They have long tails.
Discussion:
They have grey to white colour with amazingly cute furry tails. In fact, chinchillas have a rounded body, large mouse-like ears, short legs and a long tail. That is why they look like mice. A healthy baby weighs 60 to 70 grams. My brother’s are about 300 and 400 grams. Chila is larger than Chilo. My brother said that their body will grow up to 25 centrimetres long, with a tail that can add another 15 centimetres when they fully mature.
