Well don't be worried, just have to take the appropriate actions. Certainly getting a stool sample and double ziplocking it into the fridge is the most important first step. Next would be to start the rehydration process by soaking the animal in a tepid water / shallow tub. 30 - 45 minutes should be a good starting time frame bc snakes absorb considerable amounts of fluids through their cloacas. Plastic tub with airholes and a lid should suffice. Great looking ETB btw. Good job!
