Honestly I am new to ball pythons, my first was a rescue and came to me with a bad RI, crawling around with its mouth open and mucus everywhere. Every now and then even spit up mucus ( gross). I brought her to the vet, h did not culture and gave me baytril told me 0.3ml once a day orally for seven days. She wass a new snake within 5 days or so and she has been healthy ever since. But he just told me to use it till it was gone even if she was better.
