My Chameleon is 2 yrs old and was a very timmid creature. He would crawl onto my hand whenever i wanted and he would not have a problem with it.The last few days he has been acting very frightened and angry.Whenever i go into the room he puffs out and i cant get near him without him trying to bite me.he has never acted in this manner before.i live alone so there is no possibility of someone miss treating him

Please let me know what you think
