We bought a baby ball python from Petsmart about 3 weeks ago. It hasn't eaten for us, and Petsmart said it didn't eat for them. So its been without food for four weeks. We've tried not handling it, feeding it at night or during the day, in cage and out of cage, etc. We are now trying a plastic tub, 16 qts., as its habitat. (It was in a 10 gal. aquarium, with hot and cool sides.) We understand the basic tub set-up but are wondering what are ways we can get the little guy to eat and if it's necessary to take him to the vet soon.
