Thank you guys, I seriously was worried. But if you guys think it's the size of the mice that is causing this, how come this hasn't happened before when I was feeding the fuzzies? Did my snake just finally decide to show that it's grumpy?

He could have reached the "tipping point" and finally decided enough was enough and he wanted something bigger. I would try to get him on rat pups or mice that weigh about ~20 grams. I'm betting that small mouse was only about 10 grams. That was my experience when I was forced to feed Petsmart F/T. I started mine out on the small mice and they were too small pretty much right away.
