Let me actually say something...in 25 years I have never switched any snakes in my care to a separate enclosure for feeding. In all that time I have had exactly one snake that would be "after it" as soon as I opened the cage to the point that it was an issue, which was a Coastal Carpet Python (I've had other Carpet Pythons, no trouble.)
With the GTPs, if you feed at night they way they react is correct and expected.
I am curious if anybody that has been keeping snakes for a bit has had issues with multiple snakes striking out as soon as you open the enclosure?
