Our first hamster was elbino & she was the sweetest thing ever, my sister & I being young always woke her up & played with her, she never once bit us, she was 6yrs old when she passed away in my moms hands.

Then a few years after we got Snowball, a shite & black hamster & he was the meanest thing. We could pet him & it was a challenge to feed him. Once he got a hold of me cause I was trying to get his food dish & he wouldn't let go. I lifted him out of the tank set him on the couch & started to tap him on the nose & face in hopes to get him off with out harming him, I was bleeding fairly bad. That didn't work, it was as if he locked his jaws on my thumb like a pitt bull.
Saddly I had to hurt him alot to get him off, I started to pinch him all over his body, pulled on his legs, tail & ears, but it didn't work, so I yanked slow but hard on his wiskers untill he let me go. My sis scouped him up in the plastic ball & taped it shut (the door was broken). & there was blood alover the hamster, his cage, the couch, on the new rug.
My poor thumb bled forever, my sis had to call my mom from work to come over & help stop the bleeding. My mom couldn't beleave what that hamster did. The bleeding stoped 2 hrs later.
