Thanks guys. As has been stated, the suggested sizes were MINIMUM, there is absolutely no reason why you could not go larger, in fact most probably would. The fact that big breeders might choose smaller enclosures for whatever reason, is largely irrelevant to the welfare debate. Breeders necessarily need healthy animals year after year, and in most cases, good health = good mangement. Snakes (especially pythons) are sedentary, lazy animals with very economical energy needs - they don't move much if they don't have to. If they are clean, healthy and breed well, then management is probably good, even if they are in smallish enclosures.
I have pointed out in an email that the nature of the document distributed by DVD will allow the reults to be skewed by any person or group to produce a bias favourable to the desired outcome. That may be the intention.
Ahh, the things one has to do on one's birthday!
