[April]

I haven't had to deal with a dwarf who bites, in my experience it is more the Syrians who are aggressive. I've come across many who will run across the cage and bite when you are just trying to change their food and water. In these cases they just take time, patience and a good pair of work gloves. Get a thick kind so that if he does bite it won't hurt. Handle him gently on a daily basis with the gloves to get him used to the fact that you are not there to harm him. Some hamsters won't even try to bite the gloves (something about the different texture). Still make sure to let him smell you lots and lots of treats. Try not to startle him from sleep. That seems to be when they get the most defensive. I work in a pet store and have seen the most aggressive hammys end up being the sweetest ones. Good Luck!
