Thanks for the advice everyone. I will keep looking. I left the rats and his tank open for the weekend and will keep trying every night. The other teachers seem okay with this. Not too freaked out, but they also don't seem to completely believe me that he will not try and eat them. Also, you wouldn't believe the stories I am hearing about "giant man-eating ball pythons" from some people. I try and educate them, but some adults are resistant to education...
