I just switched my ball to a bigger tank about a month or so ago, and very recently started using a UTH and cage carpet and aspen bedding. She refused food for a few weeks, which I didn't think much of considering ball pythons are notorious for randomly deciding not to eat, and she finally ate again this week. But I noticed she's been soaking in her water bowl way more frequently. She had a discolored spot on her belly a few weeks ago, but then started shedding so I thought it might just be that, but I took her out of her tank today to make sure everything was okay only to find that everything is definitely not okay. Also, her shed was incomplete, which you can see in the pictures. The pictures aren't great so I'll try to get better ones.
