摘要

A housing for small pet animals such as rodents or the like has a base box with an underground passage forming member disposed in a front portion of the base box. The underground passage forming member has a front-opened underground passage portion formed like a nest-hole. A transparent front panel is disposed in front of the underground passage forming member so as to close the front-opened underground passage portion. A top board is placed on the base box so as to close the opened upper portion thereof. A lower opened cage is placed on the top board. The underground passage portion and a space in the cage communicate with each other through an exit-and-entrance opening formed on the top board.
