I don't think Pythons have evolved enough to "feel" jealousy, much less the bulk of the emotions we have. Could it have been an aggravated feeding response? My Bar-Necks do that sort of thing every time I open the cage..totally a feeding response.

I have a trio of yearling Carpets currently housed together and if I remove one the others ramp up the activity as well..again IMHO, its just a feeding response.

My White Lippeds? Forget about it. If they're out in the evening and I open the cage..right out the door looking for food.
