our corn snake

Question
We have recently moved from Virginia to Arizona and since
then our snake has eaten twice but hasen't pooped since.
Is there anything to worry about? Fed him before we left
kept him in a pillow case gave him water every few days until we arrived in Arizona.  So it's been about 5weeks since he's pooped.

Answer
Cathy, it's hard to say.  5 weeks seems pretty long.  Has it been that long since it ate as well?  Snakes will "hold back" on going prior to a shed, they do this to make themselves as large as possible which stretches the old skin.  Then right before the shed they will go (big time) which makes it easier to get the old skin off.  Give him a warm water soak if he does look like he's near a shed.
