I was feeding my CS his pinkie, When I checked back on him, when he was still in the container, he started to shake his tail (much like a rattler would ), and struck at me, I never seen him do this before, or show any sign of aggression.
Has anyone seen this behavior before?

Also, I got my CS on 12/18/06, he was 34cm long, He just shed a few days ago and its 36cm. He is only a few grams (if that much) heavier, he doesn't look thin though. Is it normal to only grow that much in 4 months or so? All the temps/humidity are right, I also have a UTH set up for him, I feed him once a week. I keep him on paper towels. Should I up the feeding to every 5 days or so?
