the other day i found my spider with substrate in his mouth i cleaned it out as best as i could then i came home after work to find him with a mouth full of substrate again i cleaned it out again then upon further inspection saw early signs of what looked liked mouth rot i have seen mouth rot before and knew exactly what to do my vet taught me what to do removed as much necrotic tissue treated him with neosporin it's mostly healed but it still puzzles me that the snake would substrate in his mouth i use bed-a-beast and never have had this happen before i would greatly appreciate any feedback on this if anyone has had this problem before
