I was wondering if anyone as a general rule of how long they can keep their beardie out of the viv when the house is chilly. Our house stays around 68 degrees in the winter so I have only been keeping Zelda out for about 1/2 an hour at a time unless she is covered on my chest. But she wants to ride on my shoulders more and more and is getting increasingly agitated at me when I put her back (grasping and clawing to stay on and puffing up at me). So is there like a general rule of thumb that people use?
