I am new to the tegu thing and I was told to ONLY use cypress mulch and nothing else for bedding is this true or is there something else we can use? Also my tegu is not completley out of hibernation yet but she did eat alittle today so How often do we change her tank bedding? I mean i know to spot clean her poop but overall how often should you clean it out ...i was also told to do so once a month? dump all the cypress mulch out and get fresh cypress mulch? Please help. Thanks
