It certainly does. I had a theory a while back about fully developed litters being born dead. I thought it was related to keeping them too warm. Another idea was that they disconnect from mothers gas-exchanging blood vessels (that's when the load shifts down) but then don't don't get out in time and suffocate. So, what you just said makes perfect sense. I did notice that live neonates are always born quite cool to the touch.

Running air conditioners this week because its hot weather. I think I'll keep their room at 68-70 F and maybe even turn off the bottom heat until the babies are born which will be any day now.
