Such accessories, as well as sufficient litter depth within which to burrow, are desirable for the pet's psychological well-being. Cages should be constructed with rounded corners to discourage chewing. Beware that glass and plastic containers drastically reduce ventilation and can lead to problems with temperature and humidity regulation. These materials make suitable cages when at least one side of the enclosure is open for air circulation. In addition, make sure that the enclosure is escape proof.
Gerbils thrive in solid bottom cages with deep bedding and ample nesting material.
Bedding must be clean, non-toxic, absorbent, relatively dust free and easily acquired. Shredded paper or tissue, pine shavings and processed corn cob are preferred bedding. Be sure that the wood shavings and ground corn cob are free from mold, mildew or other contamination before using. Do not use cedar chips or chlorophyll impregnated shavings since they have been associated with respiratory and liver disease. Provide at least two inches of bedding in the cage to allow normal burrowing behavior.
