*I'd like to state that I will be taking Nagini (my snake) to the vet regardless. I'm more so just trying to get a scope of what to expect/advice from people who also have experience with ball pythons.
*I also apologize in advance since this is my first post here and don't know how this works

I got Nagini February 5th of this year from a Petsmart. The person who sold her to me said she was a poor eater but was healthy otherwise. In addition, I was told she was female and roughly 2-3 months old (at the time I got her). From about February to late April, she would only eat anywhere from once every 2-3 weeks. I tried everything I could think of and find online such as gerbil bedding (the smell would help), etc, but nothing I did would help her eat. I'm not exactly sure what happened, but as of May, she's eating every 5-7 days (thankfully). Anyways, I'm more so posting this because I'd like to get an additional opinion on her before I take her to the vet as well as some advice. The first two photos are her now and the last one is of her when I first got her.
