My Coastal/Carpet Python has now refused food for about 6 weeks, first 2 weeks I wasn't concerned cause she ended up going into shed. But after shed she refused her meal again, which is very odd, she's a great eater.

Few things that I have noticed:

She's still very active, same behavior when she's searching the enclosure for food or wants me to open the cage and let her roam.
I changed the supplier of my food source, but I felt like I went to a cleaner and healthier supplier, don't know if she can detect something I don't?

My concern is, did I maybe increase the humidity too much during her shed and mites showed up? This is the first time I see her let some of her body sit in the water while she lays during the day, but I can't tell if she's just sitting there and its a coincidence her body is touching the water or if she's doing it on purpose, it's not all the time, or everyday and its not her whole body, small section.

Any tips on how to double check for mites, never dealt with them in the past, visually can't see anything, also nothing floating in her water.

One other thing, I got her about a year ago around this time, in March, she also refused to eat for a bit, could it be some seasonal thing?

Thanks and sorry for the long post.
