Hey guys I have some questions about your ideas when it comes to substrate. I have kept Clyde on both ground walnut and paper towels. At some point I will be upgrading him to a 4ft x2 ft x2 ft and I want some ideas about substrate. I want something that is safe but also natural looking. I know they like to dig and since I don’t let insects free roam I feel particle substrate would be ok but I want him to be safe. I was also considering ceramic tile. Please give me your thoughts.
