Again, I caution that many colubrids will not do well on a large prey diet. They will regurge and regurge and get very sick. The rule is multiple small prey items more often.
This is why this type of information needs to be given out with a heavy cautionary statement. Many species such as drymarchon, spilotes, pseustes, pituophis, thrasops, rhamphiophis, some elaphe, pseudelaphe, bogertophis etc. will have issues with large prey items. Many of these species are notorious for going downhill fast when fed large items. Drawing any sort of conclusions from this "experiment" outside of corn snakes probably is not a good idea. Knowing the issues with jani, for example, I hope that someone doesn't watch this and start feeding their deppei jani babies large meals.
So the stress would be that this was done on corns, and should not be considered wise to apply to all colubrid species.
