Well first of all.. you deal with snakes so from time to time you get the aggressive ones. I have a few myself they are no fun to deal with but they are great eaters and so I deal with it.

If your going to make a real go of being a snake keeper / Breeder get the bit thing out of your mind its going to happen and its going to happen often if you keep enough snakes.

Second a good pair of garden gloves is a good start..
