I have had a ball python now for about 7 years. I got Kane in high school and I handled him a lot. He only ever bit one person and that was my best bud Mark but it wasn't that big of a deal. Then several years went by I and I moved off to college and my parents had to take care of my snake. They fed him and watered him but never handled him. The only time he was handled was when I would come home to clean out his cage about once a month. Well this has gone on for about four years. Well I now have a house large enough that I can keep my snake with me so he has moved back in with me to finish out my last year and a half of college and I have started handling him again and now he seems very jerky and nervous. So should I start handling him more or is this a case of an old dog not learning any new tricks?
