Some time ago I mentioned that I trying several different substrates in an attempt to find the perfect substrate for indigos. After trying many including aspen bedding, carefresh, cypress, and dirt/sand/peat mix, in the end, I have come to the conclusion that good old fashioned newspaper still reigns supreme. No other substrate ensures a high level of cleanliness/hygiene like paper (when its dirty, you change the entire substrate....with other particulate types of substrates, you spot clean but still miss some of the urates that seap through the layers that go undetected and begin bacterial growth). Newspaper is cheap and is already heat sanitized. Placing several thick layers in a cage allows the indigo to use its natural burrowing tendencies. There is no chance for accidental ingestion with paper. there is no dust associated with paper unlike other substrates like aspen and cypress. Although it may not look the best, it serves my indigo's needs perfectly well. Our indigo that is on exhibit is kept on a mix of dirt/sand/peat/leaf litter which looks great and is probably my second favorite due to the aesthetic appeal....but you must be diligent when it comes to cleaning on a daily basis (and when you have 8 adult indigos at home, that becomes a real chore). In the end, everyone must do what they feel is best for their indigo but for me, I am sticking with newspaper. Rob
