I use the Aspen Sani-chips also, and love it. Spot cleaning is easy, no sharp points or splinters, when pieces do ocassionally stick to f/t feeders they are usually knocked off by the snakes mouth as it swallows, pieces that are accidentally ingested are small enough to pass through, unlike shredded aspen that gets stuck in the carpet, Sani-chips can easily be vacuumed up. Unfortunately, my supplier has decided to get out of the business, so now I need to find a new source.
