That's a challenge to supplement live feeders: you might do better if you can "gut-load" the feeders themselves- restrict food to something saturated with liquid vitamins,
& then feed soon after. Two problems with dusting powdered vits onto a live rodent: the odor of the vitamins can cause a refusal, & then even if wet* the powder mostly
falls off as the snake grabs & swallows them. *I've tried putting powdered vits onto damp f/t prey, & live prey moves a lot more than f/t. Just doesn't work very well...
Yes, you'd think a snake's skin would be a priority??? but have you ever noticed, when they get injured, they don't bleed a lot. They may have evolved to conserve blood
this way, since injuries aren't rare in the wild; I have a hunch that the slow healing is because their skin just isn't that vascular.What do you think?
