Ball pythons are shy feeders...they like to ambush their prey so they have "the upper hand". Can you imagine how he feels having a rodent shoved into his mouth?
The problem with force-feeding is that it's backwards...the prey your snake should be pouncing on now seems to be attacking him. This could make him harder to
feed in the future, not easier...it can make him afraid of his prey & more picky about what he'll accept. (Yes, I know that some do this procedure in a pinch...but I worry
about just how much skill the woman in the feed store had to do this correctly...& even so, it's a last resort, IMO.)
