I hope the guys behind the site see this and I don't have to post a somehow related video, put the question in the description, and hope to god it makes it through the hopper.
A very similar thing happened to me with baby rats and a mouse. I had them in two Habit Trail enclosures, separated by a balled-up sock. I went out for a little while, came back home and found that the rats had chewed through the sock and then beheaded the mouse. I think I was probably 8 or 9 -- it was pretty horrifying.
I didn't know that creature existed before today. Meanwhile I'll relate story. A few guys came in to build my bed and saw my guinea pig cage. "That's the biggest fucking hamster I ever saw!"
