I would take him to the vet if it were my little Ed. Also, next time you feed him, do it in a seperate container (I use the deli container that I brought him home in from the breeders's show, someone has also recommended brown paper bags) that way, they don't risk ingesting wood chips (you are using aspen or cyprus right? no pine or cedar allowed--they can be fatal to reptiles).
Anyone else got any thing better to help them more immediately?
Good luck...let us know how it goes!
