My guys don't refuse meals and I'm lucky..and I been feeding live since I forts got them and they were only a couple months old..throw the feeder in the tank and if your snakes eat,they will take care of business and should quiet quickly. That's how mine do atleast.

I bought 2 hoppers for my black pastel,about a month ago,he ate one and wanted nothing to do with the other..so I fed the other hopper to my @ the time 300 gram Ghost BP..it was funny as the hopper was as big as his head,he tried to constrict and ate it,he's a pig and loves his live rats and mice...
