My chin (Zoe) has been lying on her side a lot (but not in her house like normal). she will lay on her side on one of the inclines to another level (her cage is metal as well as the inside pieces). I do not know if this is something to be worried about? Or maybe she is just warm and the cool metal feels good to cool off? I am confused and would like to know if this is something I should be concerned with or not! Help!
