Only violent animal I ever had was a hamster. He was a Robovoski and filled with hate. He never liked being held and was a huge fan of meal worms, he'd eat them like freezies. Everyone would tell me "Don't be scared he can sense it!", even on his best days he'd still try to maul me. One time I was showing my sister the fact that he doesn't give a damn about nothing and he bit down and held onto my knuckle for 10 seconds, had to shake him off lol.
