Wow. That was a very fast vet appt with the vet very close by. Good job. What did the vet give you for the bacterial infection? Did the vet say that it was a burn? Scale rot?
As everyone else has said, you need a thermostat immediately.
I clean my cages with soap and water and then spray with chlorhexadine. I let the chlorhex sit for a couple of minutes and then wipe down and air dry.
I strongly recommend using a paper substrate for now and cleaning very thoroughly so that there is never any wetness from urine, urates, poo, or water dish spillage. Again, a thermostat is a must. Reptile Basics sells them and you can expedite shipping.
I would really love to know what the vet prescribed for your snake's infection![]()
