I don't think I ever heard of it described as "cage aggression" but rather as a feed response associated with the opening of the tub. I guess I just thought if they never associated opening the tub with direct food....well it sounds like it makes sense lol. Anyway, I'm more comfortable feeding in the big tub rather than on the substrate too but I'll be going from three snakes to five snakes and a rack system in the next few months and it all might change....![]()
