Did I do Anything Wrong?

Hey, I'm a new poster, and a new leo owner, however last night I lost my first leo. She was a month old, bought from a reputible pet store. I made sure there was the thermal gradient going, and the warm end was about 92 degrees, I fed her mealworms. I follows care sheets to figure out what to do and she seemed to be doing fine until six days ago, at which point she stopped eating all together. After about a day or two she got sluggish and slept around the clock. This continued until last night, when I found her dead.

She was a wonderful pet while I had her and I was just wondering if I had done anything wrong so I could correct that mistake for when I get another one.

Err, sorry guys, after posting, I realized I had this in the wrong section, sorry bout that.
