At our place there lives a rat Shunya. He likes to gnaw boards. My sister says that it is useful. Shunya of gray-black color. At ours rat very beautiful fluffy tail. Shuni has some habits: if it catch when it walks about the room, it climbs under a cage, and we can't get it. Shuni has a fighting character.
I give it different tasty features.
It is very healthy to live with a favourite pet! After all pets such lassies!
