Quick update: Cham survived the day! He lost 2 grams, but that may be due to making a big poop shortly before he was weighed. His poop today was poop colored, with no blood! His urine has returned to normal as well! Sadly, it looks like he'll lose the end of his tail due to the burn, but his feet have all returned to normal color. He seems so weak at times, but then he surprises me by crying when it's time to take his icky antibiotics or rolling over and rooting in the towels. I realize that this could still go either way, but every time I check on him and find him looking good my heart lifts and I'm a little more hopeful.
