So apparently, when I leave, my dragon, Betty, poops and drags her tail through it. I dont think its on purpose cuz I have seen her scurry to the other end of the tank afterwards. But When I have given her baths, the dark poo stains seem to not really come off the easily. Most of it gets off but it gets to the point of having to use pressure and she does NOT like that. Can I use anything that would be safe to get that last bit off of her? Thanks, I just don't want her to get really sick from this! :study:
