From the Zoo:

Not a cat or a dog. I want something else. And it is desirable that it does not require much care.

YYY: The Tarakans They are silent, unpretentious, breed well, create an atmosphere of family comfort, crawling onto the table during lunch and swirling with their eyebrows, welcoming the owner.

Or the mice. Beautiful gray pieces that will run around the house. And in the winter and all the beauty - lower your feet in the boots, and there warm and soft, the mice with the heat of their little bodies heated your boots.
