So I got my first ever snake back on December 27nth 2017. I got a calendar from the pet store that had the days that it did and didn't eat written on it. It hasn't eaten since the 20th of December. It is still young, not sure how young though, it is only about a foot and a half long maybe two feet at the most... I need to get a measuring tape and measure her tonight . But she hasn't eaten since the 20th, should I be worried? I've only been trying to feed her frozen fuzzy mice about once a week. Should I try live fuzzys? She also has what looks to be like a scale or dried mucus or something in her left nostril. She's had that since I got her... How should I try to get that out? She also has a slight whistle sound when she breathes, and I believe it's because of whatever is in her one nostril.

If any body could give some tips or help me out I'd greatly
appreciate it!!

I do not know whether or not she is male or female as the pet store didn't know... Looking back on it I should have gotten a snake from a breeder, but I now have her and I am not getting rid of her anytime soon
