I buy non-eating hatchlings at expos because they have heavy markdowns (as a lot of breeders don't want to bother or assume they will die). So far I have 100% success ratio getting non-eating ball pythons to eat (eventually). Sometimes people think 'ooo discount snake' and they buy them without asking the breeder (imagining they scored a deal) and they have a miserable time...
The one pictured is nothing special: a Super Pastel Het VPI Axanthic male. I'm going to keep him around until he starts eating--I don't trust anyone else to do it.
