It's healthy Pet Colors Pet Bedding. It absorbs 3 times it's weight and is non toxic. It says that it is reptile safe and recommends feeding outside cage to avoid ingestion. I find that it absorbs then distributes the humidity evenly. Leave package open for a while before changing bedding so it doesn't lower humidity initially. It is super easy to spot clean and quickly absorbs waste. I personally love it and Eden seemed quite comfortable once I made the switch. Little Soku seems comfortable as well. As for the log, he likes to use it to travel from side to side but if he changes his mind i have no qualms about removing it. Kind of wanted to actually but I get the feeling removing it would be stressful for him.
