I feed her once a week every wednesday (Its the day the local Jack's gets their rats in) so I don't think its malnutrition, i'm very religious on my feeding schedule for her, and I did just notice it over the course of about 3 days, and over the last few days her head has started to get very dull (which I can tell is getting ready for a shed) she really isn't looking much different everywhere else though, so i'm just assuming she is starting her shed process. Thanks a lot guys, I just wanted to make sure nothing was wrong before waiting for something to get very bad.

On that note, what are some good ways to increase humidity? I really need a decent mister or something.
