My BP comes out at night and knocks over the acurite thermometer all the time and my red tail boa will sit with her head on the litter dam of her cage for hours if I open the door. She waits till I pet her head and/or body. She will also stretch out the length of the cage and sit on the litter dam except she is about 5ft and her cage is 4ft so she cant completely get her whole body stretched out on it.
