I recently got a 3 yr. old cornsnake. Everytime I go into his tub to either freshen his water, or just open the tub to look in on him, he coils up and looks as if he is going to strike. He hasn't yet but that's because I've been really careful. Also, when I do just go to touch him or pick him up he twitches really bad, and he's really jumpy. Is this normal? I also got a brooks kingsnake, and she is so personable compared to what I've heard about kings. She is the sweetest thing. I just wonder why would the corn snake be so flinchy. Even after I have him out and on my lap he is always twitching. Any and all comments would be appreciated! Is there anything I can do to make him feel more at ease?
