My ball python is about 11 months old. About two weeks ago my ball has been acting very strangely, everytime i get near the cage to mist and he sees me, he shoots out from his cave in a striking pose. I cant even get him out anymore with out him striking. Last week i fed him and i went to put him back in his normal cage and he almost got my hand. today i fed him in his normal cage and he still is striking pose everytime i get near the cage. He eats evertime i offer food. I feed him about 1 large mouse a week. I even tried to increase his feeding to two mice today. He ate both. Still seems mad.
Hes most recent shed was July 26th while i was on vacation. Heat is about 90 during the day humidity around 50% average.

Anybody have any ideas what he could be aggressive about?
