OK, 3 weeks ago, my family and I bought 2 boy hamsters. We bought a cage for the hamsters together. Then a week after, both of them were fighting for water. Then a day later, they were fighting and screaming. Rolling around and fighting. I leaved them alone. Then after 10 minutes to check on them, I saw the first hamster chewing on the second hamster's head. Then, what I saw was a murder... The second hamster's head was eaten by the first hamster.You can see the spine up. It was horrible. Now, here's my question. Why??? Why does hamsters eat the other hamster's head? There was lots of food in the place where the hamsters eat. Why?
