Question? Gerbils not Sleeping in Den Boxes
I tried some research but came up with nothing...I keep reading repeatedly, in all of my gerbil care books, about gerbils liking to have a sleep den/box to have privacy, sleep, etc. I have put all number of different wood boxes and so forth in their home and while they do enjoy running in and out of the entrances, sitting on top of the boxes or just hanging inside to have a bit of private nibble time, they never ever sleep in them. My two agoutis make a big bedding pile out of their nesting materials and they sleep there...never inside any type of structure within their home/habitat. Does that happen sometimes? Just checking. Maybe they just like sleeping "outdoors" so to speak? Any thoughts?
