I don't need it open and am going to cover the sides tonight when I get home from work. I'm definitely worried she's on the cold side because it's cold and was down to 70 this morning. It's the side closest to the window and I don't think really has any more traffic than the other side. If anything the cold side is nearest the cat tree that the cat is always on. I checked the hot spot and it kept readingat 89F so I don't think it's too hot on the hot side.

I threw a blanket over that half this morning before I left and will now be worried she's gonna freeze all day until I can get back with the UTH for that side.
