Hamster's have a mind of their own. They can be as crazy as something rabed. 
   If you don't feed your hamster every day, they will bite your fingers. How? Why? Because if your little sibling sticks their finger in the hamsters cage, well, you know. Why do they bite your fingers? Because they think their little carrots. Take my advice! Good Luck!     Yours Truly,
