I have an Argente female who thinks she is a Rottweiler.
I can't even put my hand inside her cage without her literally attacking my hand! She makes hamburger out of my finger if she gets a good hold on me.
She will also bite me if I have touched any species of hamster, even if I handle her outside her cage.
I love her to peices, anyway.
I understand that she is just protecting her territory, like Souffle says.
To get her out of her cage I put a long plastic tube in her cage and let her walk up it and onto my freshly washed hands. Works everytime!
