4 month old eating cycles

[3boydragons]

How long can a 4 month old go without eating?  We've had our little guy for 3 months and he's always eaten well.  4 days ago he stopped eating.  We've put him in warm water, held him, given him fresh crickets and greens; he won't eat.  Suggestions??

Has he pooped? What's his basking temp? What type of thermometer are you using to measure that temp? What substrate (floor covering) is he on?

Temps, hydration, and UVB all play a part in their appetite. It's not normal for a little one to suddenly stop eating. Often, the problem lies in temps, hydration, or UVB. Loss of appetite can also be caused by shedding, parasites, or impaction (intestinal blockage).

Is he going gray ?  He might be starting a shed...
