My snake is going off for five months & counting... i check last years calendar & she went off feeding for 5 months exactly... i think they dont always start feeding the same months/weeks as the past year & i wouldnt worry to much until she has like 9 months without feeding... but im also kinda concern because i've noticed like a sneezing sound but she does it very rarely & i dont see any mucus or shed stuck what can it be any advice anyone?
