I think all of this is very well-intended but completely subject to interpretation: wouldn't "(c)...to exhibit normal behaviour patterns" include feeding as it would
in nature? ie. live? And the "(e) need to be protected from...suffering...& disease" would surely preclude starving your snake that won't eat f/t?
As I've said many times, I'm ALL FOR feeding pre-killed (fresh or f/t) for safety & humane considerations, but another difference is that here in the U.S. we have
many more species of native snakes. For someone like me, who used to be involved with rescue/relocation of native snakes (most often rattlesnakes), well you just
can't feed them dead food like "room service" and then send them back outside. A meal (or several) at my house meant they had the strength (energy) to have a
better chance of survival when relocated; snakes in the desert are typically struggling with survival to begin with, so food & hydration goes a long way to help
them stay alive. You'd better believe I fed them live, with no regrets. But any that weren't healthy enough to go outside, or that had to stay captive for other reasons
(too long in captivity-exposure to exotics) all got switched to dead prey, & pretty easily.
I know there are differences of perspective in this area of keeping snakes...I think this is actually a good area for discussion. You can find cruel people everywhere,
those who take a perverse pleasure in watching a snake kill a rodent, but happily that's not most of us. I think most of us just want the best for our animals.
