this is an excellent question!!! personally, i feel enrichment items (fake leaves, wood, etc) are more "important" than a huge enclosure for ball pythons.
on the flip side: a colubrid absolutely needs a larger enclosure as they like to rooooaaammm. do you think they need enrichment too?
another good question. something that kinda sucks about the hobby is that we almost have to police ourselves lest our governments try to do it for us (and do they try...). so where do we draw the line regarding enrichment and enclosure height/size? how would something like that apply to baby beeps or an established adult set in their ways?
thanks for your post!
