Very interesting pictures, and topic!
When it comes to feeding, I'm not one to have an issue with much of anything. In nature, the cycle of life and death can be quite vicious. I think it's we humans who try to soothe ourselves by making the whole feeding issue as humane as possible.
If an animal needs to eat, it needs to eat. That's just the way it is, and when we keep an animal intentionally, then it's our responsibility to keep it thriving, whether it bothers some people or not.
I do credit you for pointing out that some species aren't found in captivity often for a reason. It's easy to get carried away and want to keep anything you find. Doesn't always mean you should! A good reminder in general.
Very nice nightsnake, BTW.
