Hi there, Ive had my Veiled Chameleon coming up to 3 years and he has always a calm content lad, that loves to come out of his tank. I came home yesterday after being away for 2 nights and all of a sudden he is like a different Chameleon. Hissing and going for me (Which he has never done). He looks in good health still and is eating and drinking but i am very confused as to why the very sudden change in personalty
