I have one that is more or less hit or miss. I offer the prey item and sometimes he takes it and sometimes he won't. When I got mine about 2 years or so ago, he was from LLLReptile. My wife bought him for me as a Father's day gift-I had never seen one before and I had NO IDEA he was rear fanged, until we e-mailed the company to get more info from them as to the types of prey and care, etc. Mine of course is w/c and was LOADED with internal parasites as well as mites. Anyway, he was originally fed live mice, but I have since switched him over to f/t medium rats about every 2 weeks and he seems to eat about every other time for me. He is now very healthy and seemingly happy. Hope this helps.
