Bitsato
Junior Guinea Pig
So pne of my piggies thought that it would be a great idea to start chirping in the middle of the night.
Woke me up, at first I was a bit startled, since I didn't understand what the heck was in my room, but then I remembered - piggies! 
Not my video, but it sounded exactly like that. I'm guessing it's normal? Can't really find sure answers online.
