I just put down my deposit for my new family member who will be delivered in 15 days. I have done some research and I am sure I still have a lot to learn. I will be going shopping this weekend for supplies. We will be doing the build your own cage with the corticated floors and walls so that It will be big enough for him. I am stuck as to the litter tray or liner for this. Any advice or suggestions would be appreciated as I want to have it all set up for him. Also do you prefer a heat lamp or heating pad. I live in az so 78 degrees is not an issue that often. Thank you for any and all advice you can give me.
