I have noticed my snake has shown interesting symtoms and i want to seek other opinions before taking futher actions. But first some info.

She is 5months old, 340g.
Humidity is 55%(Day) and 70%(Night)
Temps are 90° (hot side) and 78° (cool side)
Eats F/T rats of 10-15% body weight every 4-5 days

She has for the past week made clicking noises coming from between her midsection and neck (i cant tell if it is in sync with her breathing). Also after she eats, she lunges forward violently with her mouth open and "coughs" or "gags" 1-3 times (the clicking intensifies for awhile after eating.)

But here is the issue. No bubbles, mouth appears normal, little to no saliva in her mouth, and she is eating GREAT!

Do you think she has RI? Any Tips or Treatments?
And do snakes with RI eat?? (I have heard they dont and that is why i raise this question.)

Thank you in advance! I need as many 2nd Opinions and tips as possible! ☺
