I’m not sure if folks are “hating” on out of cage feeding, the general consensus is that each keeper has to do what’s best for them and their animals, but most experienced keepers have realized it’s totally unnecessary. I agree with KMG, for those of us with larger/multiple snakes it doesn’t make any sense. I wouldn’t try to move any of my snakes that were hyped up for food either before or after they ate. That would just be asking for trouble. As far as ingesting substrate or having to remove it from their mouth, I think I’ve only done that once in 10+ years. Again, to each their own, but I wouldn’t advise anyone else to do it.
