Guniea Pig Deaths

Question
My 15 year old daughter is pet sitting for our neighbors.  They have 2 guinea pigs who have been fine all week.  She just goes over and makes sure they have food and water.  They have been moving around fine.  We live in NC and the house is set at the temperature it always is.  When she went over last night they were both sitting still . . . dead.  They share a cage.  They are a year old.  Isn't this odd?  We know nothing about guinea pigs.  Are there frequent unexplained deaths?  Do they startle easily?  Could an alarm have gone off and scared them?  We are just puzzled about this.

Hello Wendy!
Hmmm...
I know for a fact that that could not have scared them to death. I have no idea why they would both die suddenly besides being poisoned by eating something they shouldn't have. Please don't put any blame on your daughter though, I know what that feels like for a young girl.
