Yay! It's totally stable between 74 and 77 degrees.
My furnace pilot went out last night and the house temp got down to about 64 before the cooler temp woke us up. The hedgie habby didn't get lower than 70, so I think we're good. And I let the landlord know asap that the furnace needs attention, he's already in the basement getting it fixed up. I do have hand warmers and a snuggle safe heat pad for emergencies though
