IDK whats wrong w/ my corn snake!?!?!

[zookeeper2011]

I used to have two corn snakes ( bought from the same petshop) my newer one had just died about 3 weeks ago, she wouldnt eat and her butt had dried poop all around it, they think it was constipation. Ever since she died my other snake (mitchell) has not eaten for about a month and the petshops won't do anying about it, all they say is take it to a vet o give it a warm bath. I have gave it a warm bath, but there is no vet that specialize in or with snakes. IDK what 2 do!?!?!?!?!?! is he going through a stage??? he had just shed month and a half ago. and i have tried to change the temps. , dip the mouse in chicken broth, leave the mouse cold, leave the mouse warm, and put the snake in a different feeding container...do you hink it might want something othere than a mouse? Please let me know if you know anything that migt be wrong with him.
