I've got a couple like that, as well! Frank the Tank, Sharona, and Maxine were November pick ups during ReptiCon, Costa Mesa. Now they're all 3-6x's the size they were at purchase. Although, Frank eats EVERYTHING that gets put in front of her, so it's no wonder there. I'll be doing water checks and she pokes her head out of her hide like "I'm ready!" It's really interesting trying to get pictures of her when she wants to inspect the camera in case you're hiding a rat in it. lol And Maxine was supposedly strictly a mouser that has never turned down a rat for us. I'm sure the difference in prey type had a lot to do with her going from 200g to 770g. Sharona hasn't been as enthusiastic as Frank, but she's still gone from 107g to 595g. If she looked like a fatty, I'd start scaling back her rats to a smaller size, but you can still see her spine fine - it's not sunken, and she has no fat rolls - so I'm not worried about her.
