I just fed my 2 corn snakes five live hoppers each about 5 hours ago. I like to leave them in their feeding boxes for a while to make sure they eat everything. I went back to put them back in their cage and one of them was dead. No outer signs of injury or stress. Now I know it's quite ridiculous to ask for an exact cause of death on here, but does anyone have any ideas how this happened or experience with this?
