This is an interesting point and I tend to agree with it... If an animal won't eat and none of the reasons pointed out above (husbandry, ill health etc) are to blame then what is the point in force feeding it? That snake may go on to be a good feeder but may pass bad feeder genes to it's progeny.. in the wild I guess all bad feeders would be taken out of the gene pool simply by their none feeding - just my 2p worth....
