Hello Terri & welcome
Things have indeed changed. There are still many living like Dora (tough ones)
Your right not to hibernate in the first year you have them. They need to settle in and for you to get to know whats normal for them. So I would get Usain up. Dont know how big his table is but I would either block or take out his "bedroom" you can also try adding just a low watt light bulb in a clip holder or desk lamp. Not to add heat, just to try and fool him its still summer. I agree misting / hydration is very important.
Looking forward to seeing some pictures of Usain.
