Oh, one thing I forgot to mention... about having a culture done. The vet said he doesn't do cultures on snakes with RIs, because to do so you have to put them under anesthesia, and so it is cheaper and better to just try different antibiotics until you find one that works, rather than putting the snake under anesthesia with the costs & risks involved.

Do snakes really have to be put under anesthesia to get an RI culture??
