So, because one person witnessed an improved feeding response (out of 91 posts), you're worried about aggression?
For one, I definitely agree that many people who fear "cage aggression" confuse it with a good feeding response. Personally, I'm more concerned with my animals eating properly than whether I have to tap them with a hook to get them to "snap out of it." Were your snakes striking at you two days after feeding, or just on their regular feeding day, when they could smell prey? I fed my boa for 19 years in his tank, and never had him strike when there was no food around. I feed my BPs in-tub, and have no aggression issues when I handle them on non-feeding days.
