I posted this here as well because this information should be known by all gerbil owners. From: [EMAIL PROTECTED] (g. m.) The cotton balls are not safe because of the fibers, they can be swallowed or wrapped around toes or limbs. You can use bathroom tissues, which are safer. The dangers of cotton type bedding can be read on a hamster web page, here-- http://www.hamsters.co.uk/ Go to Hamster care equipment & health. Then click on Nesting Material. -- Gary's web pages - http://home.talkcity.com/StudioDr/go5
