Sorry for the loss.

I'm sorry whenever a snake dies a (likely) preventable death in captivity.

Still puzzled over the OP's statement "Our snake, is most likely sick, we think, but with what, we're not sure." That concerns me. As if the bloated belly and signs of starvation (loose, folded skin) weren't enough? That snake was either emaciated before the impaction occurred, or has been sick a very long time and yet nobody noticed before now? Surely signs were there long before the snake starved and nearly exploded. Early enough to prevent the death.

Really? not sure? That statement, along with the choice of substrate in the enclosure makes me wonder how many other things you're not "not sure" of. Looks like corncob bedding which, in spite of what the package says, is NOT digestible and is infamous for causing impaction. You may get away with using it (not the best choice) without problems but surely you wouldn't feed them with that stuff around, would you? Did you?
