Did you say you baked the bark with bleach in it? DO NOT put diluted bleach in the substrate. I don't know if anyone else has mentioned this, they probably have but cooking the substrate is enough, (At 200 degrees for two hours) diluted bleach is probably the thing that harmed the snake because you poured it in it's bedding, correct? When you use diluted bleach you NEED to rinse it off well. Please, please be careful with your next snake, don't be afraid to ask anyone on this forum for help if you're wondering anything. Perhaps you feel as though you've been treated wrongly since you seem defensive but they're really just trying to help. Also, I would suggest that you wait a a few months AT LEAST to get another snake after this incident. Don't rush, a snake is a lifetime partner who should last you around 30 years. It's like getting married, you should seriously see it as a big deal.
