Sorry if this is in the wrong place. Took our snake to the vet today because she's breathing through the side of her mouth. As soon as I noticed this strange behavior, I decided we should call a vet that does exotics. Happy to find one only 30 minutes away. She wasn't too happy to be there and get weighed. She struck the nurse and kept popping out of the tray. She does indeed have an infection, her breathing clicks and her mouth was bleeding slightly. Luckily we have antibiotics to give her. We are injecting her food with it, as she hasn't lost her appetite! I just hope we caught it early enough and that she will be okay. I don't know what could have caused this infection, as we haven't changed anything we are doing.
